Abstract
A folding-type A/D converter for converting an analog input signal to an n-bit digital code, the A/D converter having a transfer function dividing the analog input signal into at least n-1 segments, each such n-1 segment having an amplitude level corresponding to the significance of a given bit of the digital code and having linear parts which are mirror images of one another extending over 2.sup.n transition levels L. The A/D converter includes voltage-current converters for converting voltage input signals to current signals, a plurality of circuit stages for producing the linear parts in the current domain in response to the current signals, and a converter for converting the linear parts to a logic 1 or logic 0 of the bits of the digital code.
