ABSTRACT:
A zero equalization capacitor is connected to a first input of the comparator K, and at the beginning of the equalization phase, a voltage value of zero is placed at both comparator inputs, and a feedback network RN is connected between the comparator output and the capacitor, whereby the capacitor is charged to such a degree that the output signal of the comparator arrives at the decision threshold between the equality or inequality of the comparator inputs.
