It uses a dynamic threshold MOST (DTMOST) as a sensing device that periodically discharges a capacitor.

The sensor occupies only 0.017mm2 and achieves a 3σ inaccuracy of ±0.9°C from -10 to 90°C after 1-point trim. Operating from 0.85 to 1.15V, it shows a low supply sensitivity of 0.27°C/V at room temperature. It consumes 33.75µW and achieves a resolution of 10.2mK.

Its loop filter and interleaving operation are realized by fully-passive switched capacitor (SC) circuits. Its feedforward summation is implemented by using a multi-path comparator. Moreover, its overall noise transfer function (NTF) is set by device ratios and highly robust against process, voltage, and temperature (PVT) variations. It allows the loop filter poles to be placed close to the unit circle. Comparing to a recently published TI NS SAR ADC based on the error-feedback (EF) structure, this work obviates the need for amplifiers with static current, saving power. It also eliminates the dependence of NTF on the amplifier gain, which is PVT sensitive. A prototype ADC in 40nm process achieves 69.1dB SNDR over 50MHz BW while consuming only 8.5mW from a 1.1V supply, leading to a Walden FoM of 36.3fJ/conv.-step.","PeriodicalId":409525,"journal":{"name":"2020 IEEE Custom Integrated Circuits Conference (CICC)","volume":"21 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133072527","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}

With ZVS turn-on of all power FETs, the proposed converter is able to operate in the MHz range with high power efficiency in high input voltages via minimizing the switching loss. The flying capacitor further reduces the main inductor current in the step-down mode, significantly decreasing the inductor conduction loss. The proposed converter was validated using 100v e-mode GaN FETs with the on-chip gate drivers and control circuitry implemented in a HV 0.5µm BCD process. The proposed converter can support a wide input range from 9V to 45V with a maximum 48W output power, operate at 2MHz, and achieve peak power efficiencies of 98% and 96% in step-down and -up modes, respectively.

However, the use of low-power systems requires accounting for regulator losses, voltage monitors, biasing, peripheral, clock sources, and start-up energies to adapt the correct ME supply to different operation modes. Here we demonstrate a 32-bit RISC-V IMAC based microcontroller (MCU) in 180nm CMOS technology featuring a low-energy always-on (AON) subsystem extending on ME adaption by including peripherals. AON peripherals enable the MCU for low-duty-cycle sensor node applications. Low-energy clock sources and voltage monitors enable 32.768kHz to 55MHz operation and power-gate the MCU into three power states adjusted to work at the ME supply operation. Measured start-up energies using integrated RC-based oscillators show restarting energies down to 6pJ, which is 1000X less than the energy required in MCUs that apply crystal oscillators.","PeriodicalId":409525,"journal":{"name":"2020 IEEE Custom Integrated Circuits Conference (CICC)","volume":"2 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125538482","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}
