Abstract: Aspects of the disclosure provide for a circuit. In at least some examples, the circuit comprises a first amplifier, a voltage divider, a first resistor, and a transistor. The first amplifier comprises a first input terminal configured to receive a first voltage signal, a second input terminal coupled to a first node, and an output terminal. The voltage divider is coupled between a second node and a ground node and having the first node as an output node of the voltage divider. The first resistor is coupled at a first end to the second node. The transistor comprises a gate terminal coupled to the output terminal of the first amplifier, the transistor being coupled between an input voltage node and a second end of the first resistor.
