An electronic device includes two multiplexer branches, a modulation circuit, and an output interface coupled to the modulation circuit and two multiplexer branches. A first multiplexer branch generate s first output signal from a first selection signal, a first inverse signal, and a first input signal. The first inverse signal is substantially complementary to the first selection signal. A second multiplexer branch generates a second output signal from the first selection signal, the first inverse signal, and a second input signal. The modulation circuit generates a logic output signal from the first input signal and the second input signal, independently of the first selection signal and the first inverse signal. The output interface generates a multiplexed signal tracking one of the first input signal and the second input signal based on the first output signal, the second output signal, and the logic output signal.
