A dual-power rail, low-dropout, fast-response linear regulator dedicated to a wafer-scale electronic systems prototyping platform

摘要

A new dual-power rail low-dropout linear voltage regulator is presented in this paper for a 180 nm CMOS technology applied to a wafer-scale platform for electronic system prototyping. Fast load regulation is achieved with a 2.5 to 10 ns time response for voltages that range from 1.0 to 2.5 V using a dual power supply of 1.8 and 3.3 V. The overall deviation of the output sweeps from 10 to 40 mV, which is two times smaller, compared to other published topologies and the maximum load current is 20 mA. Power supply rejection ratio for the whole range of the regulator is below −30 dB for frequencies up to 1 GHz.
