Abstract
Described herein is an electronic device. The electronic device includes a unity gain buffer having an input coupled to an input node to receive an input voltage and an output coupled to an output node. A current sink circuit operates in a sleep mode in an absence of a sink current flowing into the output node, and operates in a sinking mode to sink the sink current from the output node to a reference supply node when the sink current flows into the output node.
