Abstract

PURPOSE:To obtain the switching circuit less in temperature drift, by providing the buffer amplifier which zeroes the difference between the input voltage and the output voltage. CONSTITUTION:MOS transistors 5, 6, 8a, 10 constitute the differential amplifier circuit, MOS transistor 13 and resistance 14 constitute the constant voltage circuit and MOS transistors 7,12 constitute the constant current circuit. MOS transistor 8a is used also as the power control means and control is made so that the potential difference between the input terminal 1 and the output terminal 2a can be zero. Thus, the DC voltage equal to the voltage at the analog input terminal 1 is appeared at the output terminal 2a. Further, when the rectangular wave signal having sufficiently greater amplitude is fed to the control terminal 21, the signal equal to the voltage fed to the analog signal input for peak value is obtained at the output terminal 2.
