Abstract
Shortening any of the operational phases of a noise-shaping successive approximation register (SAR) analog-to-digital converter (ADC), including the acquisition phase, the bit trial phase, and the residue charge transfer phase, can result in higher power, and it can be difficult to achieve high speed at low power. Using various techniques described, the acquisition, bit-trial, and residue charge transfer phases of two or more digital-to-analog converter (DAC) circuits of an ADC circuit can be time-interleaved. The use of two or more DAC circuits can increase or maximize the time available for the acquisition, bit-trial, and residue charge transfer phases.
