摘要
A new capacitor array structure which is both energy and area efficient is presented for a 4 bit successive approximation register (SAR) analog-to-digital converter (ADC). The proposed circuit consumes zero energy in the second and third comparison cycles. Significant lowering of energy in the different charge redistribution steps is ensured by applying different voltages in the switching scheme of the various comparison cycles. Besides energy saving to the extent of 98%, a 75% reduction in capacitance is achieved compared to the conventional method.
