Abstract :
Cyclic Digital-to-Analog Converters (DACs) can provide low power alternatives to current steering DACs for medium conversion rates. A cyclic DAC capable of achieving lite-rate DSL performance for downstream is presented in this paper. With the help of a differential bipolar architecture, the DAC delivers close to 12 bits of linearity at 4.416 MS/s conversion rate. The cyclic D/A converter, implemented in a 0.35-μm double-poly CMOS technology, dissipates only 10 mW
