Abstract :
This paper presents a CMOS Switched-Current D/A (Digital-to-Analog) converter circuit which achieves 11-bit resolution, 100 MSamples per second conversion rate, and consumes 4.4 mW, where MOSIS SCNA20 2 μm process and 3.3 V supply voltage were simulated. The developed D/A converter circuit generates 11 weighted currents using a 7-bit current multiplier circuit and a 4-bit current divider circuit. Results show that the converter circuit is well suited for low-power/low-voltage signal processing applications
