Abstract

This paper presents a CMOS switched-current D/A (digital-to-analog) converter circuit which achieves 10-bit resolution, 100 MSamples per second conversion rate, and consumes 2.3 mW, where MOSIS SCNA20 2 μm process and 3.3 V supply voltage were simulated. The developed D/A converter circuit generates 10 weighted currents using a 7-bit current multiplier circuit and a 3-bit current divider circuit. Results show that the converter circuit is well suited for low-power/low-voltage signal processing applications
