Abstract
A driver circuit may include a first node (VA), and a first circuit to generate on the first node (VA) an inverted replica of an input signal (VIN) during driver switching between a first supply voltage (Vdd) and ground, the inverted replica having a threshold voltage value based upon a reference voltage (Vref) greater than the first supply voltage (Vdd). The driver circuit may include a cascode stage (M) to be controlled by the reference voltage (Vref) and to be coupled between a second supply voltage (Vdd) and the first node, a delay circuit (D) to generate a delayed replica of the input signal (VIN), an amplifier, and a switching network (M, M) to couple a control terminal of an active load transistor (M) either to one of the reference voltage (Vref) or to ground, based upon the input signal (VIN).
