Abstract

The analog part of a current mode CMOS 5-bit bi-directional D/A converter for digital audio with 115 dB dynamic range and −90 dB distortion at 128 times oversampling is presented. A dynamic self-calibration technique based upon charge storage on the gate-source capacitance of CMOS transistors is used to obtain the required relative accuracy and absolute linearity of the current sources. A calibrated spare source is used to allow continuous operation. No laser or external trimming techniques are required.
