Abstract
In one embodiment, a pre-driver circuit comprises input circuitry connected to receive a digital input signal that alternates between an upper voltage rail and a lower voltage rail and to provide a first inverted signal that is an inversion of the digital input signal and a second inverted signal that is an inversion of the first inverted signal. The pre-driver circuit also includes actuation circuitry connected to be driven by the digital input signal, the first inverted signal, and the second inverted signal to produce a digital output signal that alternates between an upper limit that is less than the upper rail and a lower limit that is greater than the lower rail by at least an amount, wherein all transistors forming the actuation circuitry comprise a single channel type.
