1.88 nA Quiescent Current Capacitor-Less LDO with Adaptive Biasing Based on a SSF Absolute Voltage Difference Meter
An ultra-low power LDO regulator with an adaptive biasing error amplifier is presented in this paper. An absolute difference voltage meter circuit section based on super source followers is used to achieve the adaptive biasing scheme. The experimental total quiescent current consumption is as low as 1.88 nA with a measured line sensitivity of 0.13 mV/V in a circuit occupying 1473 μm² of silicon area
