Abstract

A 10-b 500MSPS current-steering CMOS Digital-to-Analog Converter with internal termination resistors is presented. In order to improve the device-mismatching problem of internal termination resistors, a self-calibrated current bias circuit is designed. With the self-calibrated current bias circuit, the gain error of the output voltage swing is reduced within 0.5%. For the purpose of reducing glitch noises, further, a novel current switch based on a deglitching circuit is proposed. A 10-bit CMOS DAC has been fabricated with a 3V 0.35um technology, and it consumes 45mW. The measured SFDR is about 65dB, when an input signal is about 8MHz at 500MHz clock frequency.
