Cyclic A/D Converter

The cyclic converter consists of a chain of identical stages, each of which senses the polarity of the input. The stage then subtracts Vref from the input and doubles the remainder if the polarity was correct. The signal is full-wave rectified and the remainder of Vin - Vref is doubled. A chain of these stages gives the gray code equivalent of the input voltage in digitized form related to the magnitude of Vref. Possessing high potential accuracy, the circuit using NE531 devices settle in 5 us.
