Abstract

PURPOSE: To enable to prevent the malfunction of logic circuit by applying alternately the voltage to a pair of differential loads for the control input signal and keeping constant the current value viewed from the power supply side.
CONSTITUTION: The input signal (a) is input to the point A, and the reference signal (b) is input to the point B, and they are compared at the comparator 1 and the control signal VCON+ having the pulse width according to the signal (a) at the point E, and the inversion signal VCON- of the signal VCON+ is obtained at the output point of the inversion circuit 2. Further, the signals VCON+ and VCON- are respectively input to the power amplifying circuits 3, 3' to obtain the signals VOUT+ and VOUT- at the output points C and D, and they are respectively fed to the differential loads 5, 5' in differential operation for the load circuit 4. Viewing the signals VOUT+ and VOUT- from the power supply side, one is OFF while another is ON to keep the current value constant. Thus, the malfunction of the logic circuit can be prevented.
