A highly efficient digital calibration method is proposed to achieve frequency stability over process variation and temperature drifts. This calibration method locks the DCO's output frequency to the reference clock of the wireless communication system during its active state. The introduced calibration scheme offers high jitter immunity and short locking periods overcoming frequency calibration errors for typical ultra-low-power DCO's. The circuit area of the proposed ultra-low-power clock source is 100μm × 140μm in a 130nm RF CMOS technology. In measurements the proposed ultra-low-power clock source achieves a frequency stability of 10 ppm/°C from 10 °C to 100 °C for temperature drifts of less than 1 °C/s with 80nW power consumption.","PeriodicalId":246471,"journal":{"name":"ESSCIRC Conference 2016: 42nd European Solid-State Circuits Conference","volume":"31 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127172475","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}

Redundancy and coarse foreground calibration mitigate MSB comparators offset mismatches. A novel background calibration loop matches LSB comparators offsets to a reference comparator. The proposed scheme avoids a dedicated calibration cycle that would slow down conversion. Additionally, it ensures input common mode voltage tracking for each comparator during both calibration and normal operation, without requiring external inputs or special DAC configuration. This enabled the use of a simple bidirectional single-side switching scheme to eliminate switching logic which further boosts speed and reduces switching power.

A 1kb nonvolatile SRAM (NV-SRAM) array with the peripheral circuits is implemented using 65nm silicon-on-thin-buried-oxide (SOTB) technology. The energy performance of the NVPG architecture for NV-SRAM is systematically analyzed based on important circuit parameters extracted from the chip. The energy efficiency evaluated by break-even time (BET) is strongly affected by the array structure and its peripherals. The body-bias-induced leakage reduction for the peripherals is highly effective at reducing BET.

To achieve better switching behavior and lower EME in inductive switching applications, very precise gate control of the power MOSFETs by the gate driver is required. The driver presented in this paper can operate at voltages up to 60V, and it is able to change the gate current in 10 / 15ns (rise / fall delay) within a range of 20mA to 500mA. Achieved by a class B buffer in the output stage, this enables multiple current changes in a 100ns switching transition. A dip in the output current, caused by parasitic capacitances, is reduced from 80% of the full scale current to 20% by a cascode configuration in the driver output stage. The gate voltage is clamped to 11.5V, with a precise clamping circuit to reduce RDS,on with the full gate current, but without stressing the gate oxide with any over voltage. By fully integrating this concept in 130nm HV-BiCMOS, a reduction in external components for limiting overshoot, stress and EME can be achieved.","PeriodicalId":246471,"journal":{"name":"ESSCIRC Conference 2016: 42nd European Solid-State Circuits Conference","volume":"29 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130526012","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}

The micro power supply consists of a fully integrated ACDC and DCDC converter with one external low voltage SMD buffer capacitor. The micro power supply is fabricated in a low cost 0.35 μm 700 V CMOS technology and covers a die size of 7.7 mm2. The use of only one external low voltage SMD capacitor, results in an extremely compact form factor. The ACDC is a direct coupled, full wave rectifier with a subsequent bipolar shunt regulator, which provides an output voltage around 17 V. The DCDC stage is a fully integrated 4:1 SC DCDC converter with an input voltage as high as 17 V and a peak efficiency of 45 %.
