Abstract

Aspects of the present disclosure provide for a circuit. In at least some examples, the circuit includes a first switch coupled between a first node and a second node and a second switch coupled between a third node and the second node. The circuit further includes a resistor coupled between the second node and a fourth node and a capacitor comprising a first terminal coupled to the fourth node and a second terminal. The circuit further includes a transistor comprising a drain terminal coupled to the third node, a source terminal coupled to a fifth node, and a gate terminal and an amplifier comprising a first input terminal coupled to the fifth node, a second input terminal coupled to the fourth node, and an output terminal coupled to a sixth node.
