Replica biased voltage regulator

摘要

A replica biased voltage regulator circuit ( 100 ) is disclosed that provides high frequency response via local positive feedback and low frequency response via a negative feedback loop. A voltage regulator circuit ( 100 ) can include current conveyor ( 106 ) that essentially forces an output voltage (Vload) to follow a replica voltage (Vrep). An operational amplifier ( 102 ) can provide negative feedback by controlling current supplied to the current conveyor ( 104 ) based on a comparison between a reference voltage (Vref) and the replica voltage (Vrep).
