Abstract

PURPOSE:To provide a comparing circuit with hysteresis characteristics without influencing an input signal by providing the control circuit of an internal combustion engine ingition device with the comparing circuit which compares two input signal voltages and equipping a feedback circuit for comparison characteristics. CONSTITUTION:A comparing circuit A20 compares the values of input signal voltages applied to two input terminals to generate an output voltage at an output terminal 5. A feedback circuit A40 is provided to obtain hysteresis characteristics as the comparison characteristics of the circuit A20. This circuit A20 has a feedback terminal A13 which relates to one of said input terminals A11 and A12, i.e., A11 and is independent of the input terminal in terms of impedance, and the output of the feedback circuit A40 is supplied to the terminal A13.
