High-Performance Resistorless Sub-1V Bandgap Reference Circuit Based on Piecewise Compensation Technique

摘要

A piecewise compensated sub-lV CMOS bandgap reference without using any resistors is presented. The design reduces the silicon chip area with improved circuit robustness. The bandgap reference is simulated with Spectre using SMIC 0.18 mum CMOS technology.
