摘要

An ultra-low power, low-noise, high power supply rejection (PSR) op-ampless regulator is presented in this paper. It uses a native composite power transistor plus a sandwich on-chip native capacitor in the pre-regulator to enhance broadband high PSR performance. Besides, a pseudo-resistor based low-pass filter is used to reduce the Brokaw''s voltage regulator circuit noise. Realized using GlobalFoundries 1.8V/3.3V CMOS 0.18µm process, the regulator gives a mean output 0.992V for 8 samples while occupying a silicon area of 0.095mm
