Improved Successive-Approximation ADCs With Charge Balancing

Improved successive-approximation analog-to-digital converter (ADC) circuits are undergoing development for eventual incorporation into focal-plane arrays of photodetectors. These circuits are derived from, and offer advantages over, the ones described in "Successive-Approximation ADCs With Charge Balancing" (NPO-19784), NASA Tech Briefs, Vol. 21, No. 5 (May 1997), page 47.
