ABSTRACT:
An analog-to-digital converter having: (1) a quantization stage which received an analog input signal and has separate output terminals for different threshold levels; (2) a discriminator stage for exclusively using the highest threshold output terminal of the quantization stage to produce on a a corresponding output terminal of the discriminator stage a signal of one binary logic state, all the other output terminals of the discriminator stage having the opposite binary logic state; and (3) an encoder stage connected between the output terminals of the discriminator stage and a smaller number of digital data output terminals to produce a pure binary number which represents the output terminal of the discriminator stage that is at the one binary logic state.
