Abstract

PURPOSE:To obtain stable output, by feeding back the output of the post stage comparison circuit to a terminal given with the reference voltage of the prestage comparison circuit, in a level comparison circuit giving the output of the comparison circuit at the prestage to the comparison circuit at the post stage. CONSTITUTION:When a signal with a level exceeding the reference level is applied to an input of a comparison circuit 1, the output of a comparison circuit 2 goes to +V. Since the output of the circuit 2 is at +V, the reference voltage of the circuit 1 is increased with the operation of resistances R3 and R2. In this case, before the input signal is increased, since the reference voltage is increased even if it is slightly lower than the before that increase, the output of the circuit 2 can keep +V.
