Following on from Part 1, presented here are eight more unique, and pertinent design applications for low Iq.

A Low-Leakage-Retention LDO and Leakage-Based BGR with 120-nA Quiescent Current

This low-dropout (LDO) bandgap regulator (BGR) maintains very-low-leakage current consumption that lowers overall power consumption without the use of traditional bipolar junction transistors (BJTs).1 A 55-nm, 1-V CMOS process is employed in this design.

Ultra-low-power structures used in the design enable lower power-supply rejection ratio (PSRR) performance as compared to the other structures. This unique structure doesn’t apply any off-chip capacitor.
