Abstract

PURPOSE:To enable mass production, by making the control characteristics uniform through the control of load capacity by an amplification type inverter. CONSTITUTION:The output of an amplification type inverter 5 is fed back to the input via a crystal oscillator 4 and is operated as an oscillator. The control of an oscillation frequency is made by varying the load capacity consisting of capacitors 1, 3 and an amplifying type inverter 6 by a variable voltage generating source 10. The output impedance can continuously be changed within the variable range of a control voltage applied to the input.
