Abstract
A circuit of a monolithically integrable MOS-comparator has a capacitor, a signal input and a reference input of the comparator being alternatingly connected to the capacitor via respective first and second clock-controlled transfer transistors, a first amplifier stage having a control input and an output, the capacitor being directly connected to the control input and being also connected via a third transfer transistor to the output of the first amplifier stage, a second amplifier stage having a control input and an output, the output of the first amplifier stage being further connected via a fourth transfer transistor to the control input of the second amplifier stage. A third amplifier stage identical with the first and second amplifier stages has a signal input and an output, the output of the second amplifier stage being a first signal output of the comparator and being also connected to the signal input of the third amplifier stage. The output of the third amplifier stage as a second signal output of the comparator and as connected via a fifth transfer transistor to the control input of the second amplifier stage. Means for transmitting two clock signals are connected to the…
