This letter presents a relaxation digital-to-analog converter (ReDAC) configuration with positive and negative polarity output with high pass filter (HPF). Its digital input is provided in two’s complement format, to which the proposed ReDAC configuration directly matches. The configuration and principle are shown and the operation has been verified with SPICE simulation. The proposed ReDAC with HPF is an extension of the conventional ReDAC using low-pass filter (LPF) which generates an analog output with only positive polarity.
