Abstract: Aspects provide for a circuit including a voltage supply, a driver, and a feedback bias circuit. The driver includes a first p-type field effect transistor (FET) and a first n-type FET. The voltage supply has an input and an output. The driver has a first input coupled to the voltage supply output, a second input coupled to a first node, and an output coupled to a second node. The first p-type FET has a gate coupled to the output of the driver, a source coupled to the voltage supply output, and a drain coupled to the second node. The first n-type FET has a gate coupled to the output of the second driver, a drain coupled to the second node, and a source coupled to a ground node. The feedback bias circuit has an input coupled to the second node and an output coupled to the voltage supply input.
