Abstract
PURPOSE: To reduce not only the operation error but the temperature of the output voltage, by producing the desired cycle waveform through switching of the input resistance and then varying the amplitude of the output voltage in proportion to the control input voltage.
CONSTITUTION: A number of branches consisting of the serial circuit of the input resistances Ri1WRin plus the electronic switches S1WSn are provided between the terminal to which the control input voltage ec and the input terminal of the operation amplifier OP. Then the switches S1WSn are made to conduct successively by the pulse distributor PD to which the clock pulse es is supplied. The resistance value is selected previously to an appropriate level for the resistances Ri1WRin which are made successively by the switches S1WSn. As a result, the desired cycle function waveform can be extracted out of the output terminal of the operation amplifier OP in the form of the output voltage eo simulated with a staircase form. In this case, the amplitude of the voltage eo can be varied in proportion to the voltage ec. Thus the operation error and the temperature drift of the voltage eo can be reduced.
