Comparison of the RC-Triggered MOSFET-Based ESD Clamp Circuits for an Ultra-low Power Sensor System
This paper uses the RC-triggered MOSFET-based electrostatic discharge (ESD) power clamp to conduct ESD from ESD events and not affect the ultra-low power sensor system. Then using the stacked device include stacked MOSFET or stacked BJT to reduce the leakage current which increases with temperature. Moreover, we compare gate-driven method and two-level–driven with both gate-driven…
Read More A Resolution-Reconfigurable Asynchronous SAR ADC with Segmented and Non-Binary Weighted Capacitance DACs
With the addition of thing of internet applications to 5G smartphones, mobile standby time and ultra-low-power sensing systems have become increasingly important. Nowadays, such sensing systems typically reduce power consumption to microwatts. This paper presents segmented and non-binary weighted capacitance DACs, low power, high resolution, an asynchronous clock, a spark-detect, vcm-based switching and direct switching,…
Read More A Resolution-Reconfigurable and Power Scalable SAR ADC with Partially Thermometer Coded DAC
Power consumption is becoming more and more important in the Internet of Things (IOT). The ADC is the main power hungry in multi-sensor electronic systems and effectively reducing ADC power consumption without affecting ADC characteristics is an important. This paper is extended from the conference paper. The segmented SAR ADC presents reconfigurable 9 to 12-bit…
