Creative Spins on Low-Iq Applications and Designs (Part 2) (Download)

Feb. 9, 2023

Read this article online.

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.
