Digital-to-analog converter, digital-to-analog conversion system, electronic system, base station and mobile device

Abstract

A digital-to-analog converter is provided. The digital-to-analog converter includes a delay circuit configured to iteratively delay a digital input signal based on a clock signal for generating a plurality of delayed digital input signals. Further, the digital-to-analog converter includes a plurality of groups of inverter cells. Each group of inverter cells is configured to generate a respective analog signal based on one of the plurality of delayed digital input signals. The inverter cells includes a respective inverter circuit configured to invert the respective delayed digital input signal. The plurality of groups of inverter cells include different numbers of inverter cells. The digital-to-analog converter additionally includes an output configured to output an analog output signal based on the analog signals of the plurality of groups of inverter cells.
