Digital-to-analog converter

摘要

A digital-to-analog converter is composed of a first array of capacitors for generating an analog voltage corresponding to the code value of a digital input signal, and a resistive voltage divider for dividing a reference voltage and applying a divided voltage to the first array of capacitors. The digital-to-analog converter also includes a second array of capacitors for applying a corrective voltage to the first array of capacitors and a memory circuit for controlling the second array of capacitors.
