HIGH UNITY GAIN BANDWIDTH VOLTAGE REGULATION FOR INTEGRATED CIRCUITS

摘要

An integrated circuit voltage regulator uses a simple CMOS structure to implement a High Unity Gain BandWidth voltage regulator providing for low voltage ripple at the output of the regulator up to high frequencies in the hundreds of MHz range. A transconductor first stage is followed by an impedance cancellation second stage allowing DC gain to be set completely independently of the bandwidth.
