ANALOG-TO-DIGITAL CONVERTER CIRCUIT

摘要

In an analog-to-digital converter circuit comprising a comparison circuit per tap of a potential divider. The comparison circuits are arranged in groups each controlling a respective differential amplifier. In a group only one output of each comparison circuit is connected to an output of the subsequent comparison circuit operating in the opposite sense and the odd outputs of the group of outputs thus obtained are connected via a first group of emitter followers to a first input of one of the differential amplifiers, while the even outputs are connected via a second group of emitter followers to a second input of this differential amplifier.
