Abstract: A circuit includes: a first load circuit and a second load circuit coupled in parallel between a first node and a reference voltage node, where the first load circuit and the second load circuit are configured to receive a first input signal and a second input signal, respectively; a first pass device and a first switch coupled in series between a voltage supply node and the first node; a second pass device and a second switch coupled in series between the voltage supply node and the first node; and an amplifier, where a first input terminal and a second input terminal of the amplifier are configured to be coupled to a reference input voltage and the first node, respectively, where an output terminal of the amplifier is coupled to a first control terminal of the first pass device and a second control terminal of the second pass device.
