Abstract
This disclosure provides systems and apparatuses for converting a single-ended analog signal into a differential analog signal. In some implementations, a single-ended to differential signal converter may include an N-path filter to generate a 180 degree phase-shifted version of a single-ended input signal. The single-ended input signal and the 180 degree phase-shifted version of the single-ended input signal together may form a differential signal. In some implementations, the N-path filter may delay the single-ended input through a series of switched capacitors.
