Abstract:
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.
