Abstract
A circuit of an output stage of a push-pull driver having dynamic biasing may include a stacked configuration of field effect transistors (PFETs) having a first PFET, a second PFET, and a third PFET, whereby the first PFET is connected to a first supply voltage, the third PFET is connected to an output of a switchable voltage bias generator circuit, and the second PFET is electrically connected between the first PFET and the third PFET. A transmission gate may be connected to a second supply voltage, whereby the transmission gate electrically connects the second supply voltage to an electrical connection between the first PFET and the second PFET based on a first operating state for preventing a voltage breakdown condition associated with the stacked configuration of PFETs. The third PFET is bias controlled via the switching of the output of the switchable voltage bias generator circuit.
