Abstract

PURPOSE:To attain the automatic control to the optimum value of a circuit by providing a delaying circuit and a voltage comparing circuit at a voltage converting circuit having a secondary function characteristic. CONSTITUTION:A voltage converting circuit 1 to output a voltage converted by a prescribed converting function for an input voltage is composed of a non-control circuit having a secondary function output voltage in accordance with an input control voltage. A delaying circuit 2 to delay for a constant time for the input voltage delays the output voltage while the output of the converting circuit 1 is connected to the input. By a voltage comparing circuit 3, the output of the voltage converting circuit 1 is connected to one side input terminal, the output of the delaying circuit 2 is connected to other side input terminal, both output voltages are compared and the size is decided. For a differential amplifying circuit 4, the output of the voltage converting circuit 1 is connected to one side input terminal, the output of the voltage comparing circuit 3 is connected to other side input terminal and the action direction of a control voltage is determined. The output of the circuit 4 is connected to the input of the voltage converting circuit 1. Thus, the output voltage for the input voltage is automatically controlled to the optimum value of the circuit having an optimum value.
