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).
