A viable popular approach is to exploit multicore mode-switching VCOs for two reasons: (1) their PN improves linearly by in-phase coupling of N identical VCOs; (2) the resonant-mode switching enhances the VCO FTR without degrading the tank quality factor (Q) as no RF current ideally flows through lossy mode-selection switches. However, it is still challenging for dual-mode VCOs to achieve a competitive FoM while covering an octave FTR at oscillation frequencies $(mathrm{F}_{text{OSC}})$ above 6GHz [1]. To enhance the number of oscillation modes to 3, [2] added a center-loop inductor $(mathrm{L}_{mathrm{C}})$ to a transformer, as shown in Fig. 9.2.1. However, a large FTR gap is measured, since the transformer windings should be strongly coupled to accommodate $mathrm{L}_{mathrm{C}}$, The authors of [3] and [4] realized a triple- and quad-mode operation, respectively, by coupling two individual transformer-based resonators (see Fig. 9.2.1). Apart from the large area penalty, the former needs an extra third winding $(mathrm{L}_{mathrm{T}})$ in each transformer that degrades the tank Q, while the latter used large, fixed coupling capacitors $(mathrm{C}_{mathrm{M}})$ that load the tank in two of the resonant modes, thus limiting the VCO FTR.","PeriodicalId":6830,"journal":{"name":"2022 IEEE International Solid- State Circuits Conference (ISSCC)","volume":"23 1","pages":"1-3"},"PeriodicalIF":0.0,"publicationDate":"2022-02-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"91228414","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, a high-frequency RO suffers from inferior phase noise, which is exacerbated by its high flicker-noise corner [1], being unsuitable to be a precision-timing clock source for a high-throughput interface. While injection locking widens the noise-suppression bandwidth of an RO-based phase-locked loop (PLL) [2], its effectiveness to overall jitter is limited only to those with low multiplication factors. By exploiting the accumulation-free nature of jitter in delay-locked loops [3], the reference multiplier in [4] generates a clean mid-frequency clock and then is cascaded to a high-frequency PLL, achieving a low output jitter despite a high multiplication factor. However, the background calibration for the large delay errors in the reference multiplier due to process, supply voltage, and temperature (PVT) variations necessitates an excessive settling time, which is in the order of a few milliseconds at worst. While the reference multiplier in [5] achieves very low noise, its calibration, which also requires a long settling time, should be preceded by a post-fabrication trimming. In [6], another viable method for reference multiplication is presented. However, the long calibration time remains unsolved due to the required low noise contribution of its calibration PLL. In this paper, we present a 100MHz-reference, 8GHz/16GHz RO-based injection-locked all-digital PLL (IL-ADPLL) that incorporates a reference octupler (8xREF) with a probability-based adaptive calibration algorithm.

Meanwhile, the increasing cost in advanced technology nodes favors area-efficient ADC architectures. The traditional voltage-domain time-interleaved (TI) SAR ADC [1]–[2] is a popular choice for its superior power efficiency. However, its single-channel sample rate is generally limited to <1GS/s, necessitating a large number of TI channels in high-sample-rate scenarios. It inevitably increases implementation overhead, including capacitive loading to the input driver and total area consumption. Recently, time-domain ADCs [3]–[5] have shown promising sampling speed, but are mostly based on thermometer coded time-to-digital converters (TDC). Unfortunately, the circuit complexity for such Flash TDC grows exponentially with the target bit resolution. Existing SAR TDCs [6] demonstrate a lower complexity but are generally limited in sample rate (MS/s). In this work, we propose a two-step time-domain ADC that uses a first-stage Flash TDC with the residue time quantized by the second-stage SAR TDC, targeting the >GS/s regime. To further improve the throughput of SAR TDC conversion, we propose a delay-tracking pipelining technique that allows the SAR TDC to quantize two residue time samples, simultaneously. At the circuit level, we use a selective delay tuning (SDT) cell to provide the time reference required for SAR conversion without using an excessive number of delay stages. A proof-of-concept ADC prototype in 14nm CMOS technology with 2x time interleaving achieves 10GS/s with 37.2dB SNDR at Nyquist frequency.

However, they have two inherent issues. The first is that their jitter performance is sensitive to PVT variations. To address this problem, recent RO-ILCMs have been equipped with a multi-purpose, real-time digital calibrator that can remove both the frequency error of the RO and the phase error of the calibrator [1]–[2]. The second is that their operational stability and jitter performance degrade rapidly as the multiplication factor, N, increases. This issue, which has yet to be well addressed, is rooted in the fundamental limitation of the typical injection-locking method, i.e., injecting narrow pulses into the RO (top left of Fig. 13.2.1). When the free-running frequency of the RO deviates from the target frequency, $Nf_{text{REF}}$, where $f_{text{REF}}$ is the frequency of the reference clock $(mathcal{S}_{text{REF}})$, the core current of the RO $(I_{text{osc}})$ and the $text{injecting}$ current $(I_{text{INJ}})$ should be out of phase to satisfy the oscillation condition by creating the necessary phase shift. Thus, the effective magnitude of $I_{text{INJ}}$ at $N f_{text {REF, }} text {i.e}., I_{text{INJ,eff }}$, relative to $l_{text{osc}}$ determines the maximum phase angle, $phi_{text{MAX}}$, and, thus, the maximum lock range, $omega_{mathrm{L},text{MAX}}$ [3]. However, for a large $N, I_{text{INJ,eff} }$ becomes extremely small, sharply reducing $phi_{text{MAX}}$ and $omega_{mathrm{L},text{MAX}}$. Although the RO-ILCMs in [4]–[5] achieved a total $N$ of over 40 by using a reference doubler or quadrupler, their two-stage operation offers limited improvement of the jitter $text{FoM}$. MDLL-based implementations are better suited for larger N, but the time required for edge switching limits the maximum output frequency, $f_{text{OUT}}$, and the value of N.","PeriodicalId":6830,"journal":{"name":"2022 IEEE International Solid- State Circuits Conference (ISSCC)","volume":"36 1","pages":"1-3"},"PeriodicalIF":0.0,"publicationDate":"2022-02-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"90585256","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In high-performance commercial and defense radios, CMOS mixers place critical limitations on receiver linearity as the LNA output typically compresses the mixer, leading to recent work on mixer-first approaches in CMOS to improve receiver linearity [1].

In addition, low form factor and decent transient responses are also favorable for such applications. Prior state-of-the-art designs either use single-stage hybrid designs using multi-level or Dickson converters [1 – 3], or adopt two-stage cascaded architectures with a highly efficient unregulated front (or rear) stage [4], as shown in Fig. 18.6.1 (left). The multi-level designs, which conduct the full inductor current through all the on-state switches, are suited to low-to-medium power levels with limited current density. The Dickson converters take advantage of a high conversion ratio, however, at the cost of reduced output voltage range. The two-stage designs which show decent output range and efficiency, however, can suffer from heavy load efficiency degradation considering that the efficiency of both stages degrade with increasing load and the overall efficiency which is the product of the efficiencies of the two stages is severely degraded. Inspired by the inductive-sigma converter [5] which shunts a highly efficient unregulated LLC with a regulated Buck, this work proposes a reconfigurable capacitive-sigma converter. By input-series and output-shunting a highly efficient unregulated switched-capacitor (SC) converter with a reconfigurable Dickson hybrid Buck stage, the power stage input current is reused and output currents are combined. Therefore, the overall efficiency is greatly improved in a wide continuous VCR range and with an enhanced loading capacity.
