Black in 1928 described the principle of negative feedback using two functions denoted as A(s) and β(s). While negative feedback has many important practical benefits, circuits that utilize this principle can go unstable. In 1932 H. Nyquist described the conditions that maintain stable behavior based on the complex behavior of the product of A(s) times β(s) culminating into what is referred to as the Nyquist Stability Criterion. When applied to electronic circuits, however, there is uncertainty in identifying A(s) and β(s) due to circuit loading effects. In this paper, a theory of stability will be introduced that takes into account the influence that input and output circuit loading effects have on the operation of the circuit.

In this paper, we devise a platform for readout of MTJs that rely on analog circuitry with relaxed specifications, while part of the system complexity is leveraged to digital post-processing. The proposed system comprises a high-density array of 64 × 64 MTJs that are readout by 4 acquisition channels which comprehend mismatch correction, amplification, filtering and data conversion. In order to handle the expected large spreads that result from fabrication mismatches in high-density MTJ arrays, we introduce a pre-calibration procedure that enhances the signal processing dynamic range, enabling the usage of medium performance electronics while leading to high-quality images even in the presence of weak magnetic fields. Finally, we discuss how a proper sampling strategy may lead to improved imaging noise performance, especially in regards to low-frequency (flicker) noise with virtually no drawbacks. A mathematical model is used to estimate the noise performance, which is contrasted to extensive transient noise simulations in a 180 nm commercial CMOS process and enable the assessment of the proposed techniques. We show that the proposed system is able to acquire each pixel with an input-referred noise of only 55 µV, while the input signal range in our application is only 2.34 mV.","PeriodicalId":373745,"journal":{"name":"2021 19th IEEE International New Circuits and Systems Conference (NEWCAS)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-06-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131676914","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}

Comparator noise and offset have critical impact on overall ADC performance, thus requiring a careful comparator characterization routine. Due to the dynamic nature of such circuits, the performance assessment becomes a challenging task when relying on conventional simulation-based analysis. In this paper two alternative approaches to simulate dynamic comparator noise and offset are discussed. By relying on periodic steady-state (PSS), periodic transfer function (PXF) and periodic noise (PNOISE) analyses the noise of a dynamic comparator can be obtained in a fraction of the time when compared to traditional transient noise simulations. A binary-search-based Verilog-A Offset Tester block is also presented as a mean to speed-up the offset characterization. The PSS + PXF + PNOISE method achieves a 220× decrease in simulation time, while the Verilog-A Offset Tester allows a 60× simulation time reduction.","PeriodicalId":373745,"journal":{"name":"2021 19th IEEE International New Circuits and Systems Conference (NEWCAS)","volume":"51 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-06-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116158841","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}

Tuning the tank circuit is design challenging. In this paper signal isolation in the AC switch driver is presented to implement an auto-tuning system that uses synchronous switched capacitor to control the resonant frequency of the tank circuit of a half-bridge voltage fed resonant converter to power HIFU. Capacitive coupling is proposed as signal isolation instead of classical technique due to compatibility with MRI regulations used in its vicinity, avoiding bulky magnetic components. The proposed circuit works under 5V voltage and consumes 1.45mW power. With input signal frequency of 1MHz and a carrier frequency of 100MHz, the observed output signal delay is only 10ns, i.e. 1% of the signal period. The proposed circuit is designed and simulated in a CMOS 0.35μm technology.

The transmitter (TX) part consists of a voltage-controlled oscillator (VCO), a fractional-N phase-locked loop (PLL) and an output buffer for OOK modulation. The receiver (RX) front-end implemented based on a low intermediate-frequency (IF) homodyne RX architecture comprises a balun low-noise amplifier (LNA), a Gilbert mixer and a variable gain amplifier (VGA). The RX re-uses the signal generated by the TX as its local oscillation (LO) signal. A proof-of-concept circuit prototype has been fabricated in a 180-nm BiCMOS technology. Experimental results show the PLL frequency can be adjusted over the entire MICS band with a frequency resolution of 0.33 MHz. Its phase noise is -100 dBc/Hz at 1-MHz offset frequency. Additionally, the TX exhibits a maximal output power of 4.6 dBm. The complete RX front-end achieves a noise figure below 8.4 dB and a high conversion gain of 75 dB. The TX and RX consume a DC power of 23 mW and 27.5 mW, respectively.
