Abstract:
1. A method of generating a combined output signal, comprising: converting a single-ended input signal into first and second differential signals using a first pair of differential amplifiers, wherein the second differential signal is isolated from the first differential signal and wherein the first and second differential signals are based, at least in part, on a same reference signal; applying the first and second differential signals to a second pair of differential amplifiers to generate first and second output signals including providing the first differential signal from a P-type differential amplifier to an N-type differential amplifier and providing the second differential signal from an N-type differential amplifier to a P-type differential amplifier, wherein each of the second pair of differential amplifiers is configured to swing between first and second supply voltages; and combining the first and second output signals to generate the combined output signal.
