Supply-Noise-Resilient Design of a BBPLL-Based Force-Balanced Wheatstone Bridge Interface in 130-nm CMOS

An energy-efficient and supply- and temperature-resilient resistive sensor interface in 130-nm CMOS technology is presented. Traditionally resistive sensors are interfaced with a Wheatstone bridge and an amplitude-based analog-to-digital converter (ADC). However, both the unbalanced Wheatstone bridge and the ADC are highly affected by supply voltage… (More)
