  • Replica biased voltage regulator
    Patent number: 7026802
    Abstract: 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).
    Type: Grant
