Webbthe 15-level thermometer DAC for linearity improvement. The fine SAR ADC takes 8 cycles to convert 7b, which relaxes the DAC settling requirement during conversion. The ADC uses a 50% duty cycle for sampling, 25% for SAR conversion, and 25% for residue amplification. During the sampling phase, the WebbThermometer-Code DACs (Cont.) • Total area required by the transistor switches is the same (compared to binary-weighted) All transistor switches are of equal sizes since they all pass equal currents • Examples 1. thermometer-code resistor DAC Binary-to-thermometer code conversion b 1 b 2 b 3 d 1 d
