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

Integrated driver and related method

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).
