ABSTRACT:
One embodiment in accordance with the invention is a circuit. For example, the circuit can include a first stage amplifier coupled to receive a reference voltage. The circuit can also include a second stage amplifier coupled with an output of the circuit and the first stage amplifier. Note that the output can be fed back to the first stage amplifier. Additionally, the circuit can include a module coupled with the second stage amplifier and can restrict current flow to the second stage amplifier and the output provided the circuit is in a sleep mode. Furthermore, the module can drive a terminal of the second stage amplifier to a logic low voltage provided the circuit is in the sleep mode.
