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-...
