Abstract

The circuit shown in Figure 1 is designed to do an e-bit successiva approximation analog.to-digital conversion In 8 clock cycles. This improves the number of conversions per second of the circuit Over most commercial S/A A/D devices which require 9 clock cycles to complete the same conversion. The same technique may be used to construct any S/A A/D converter with N bits of resolution. In this case the conversion will require N clock cycles rather than N + 1 clock cycles as required by the widely used cow figuration.
