Abstract :
A new low-power capacitive structure and its switching scheme for Successive Approximation Register (SAR) Digital to Analog Converter (DAC) is presented. The proposed method reduces power consumption by 93% and area by 50% compared to the conventional binary-weighted DAC. Moreover, only one reference voltage is used to avoid the effect of common mode voltage (Vcm) non-idealities on precision.
