Filed: 1990-05-31
Abstract: 2.1 Comparators, on the input signal of which high-frequency oscillations are superposed, tend towards overshoots in the vicinity of the switching threshold, which can be prevented by a capacitor of relatively large capacitance at the input of the comparator. Because of the high capacitance, such comparators cannot be produced as ICs. 2.2 To achieve a comparison circuit which is both overshoot-free and can be produced as an IC, the input signal (U) is supplied to one input of a transductance amplifier (V), the output of which is connected to an integrator (I) and at the other input of which a first reference quantity (Ref 1) is present. The output of the integrator (I) is connected to one input of a comparator (K1), at the other input of which a second reference quantity (Ref 2) is present. At the output of the comparator (K1), an overshoot-free signal (D) can be picked up which can be used, for example, for controlling a switch. 2.3 Comparison circuits with overshoot-free output signal which can be produced as ICs. <IMAGE>
