Title: Voltage controlled oscillation circuit
Inventor: MIYAMAE RYUICHI
IPC: H03B5/32
Filed: 1990-02-20
Abstract: PURPOSE:To obtain a voltage controlled oscillation circuit whose operation is stable even when a control voltage is changed by making a capacitance of a load capacitor connected between a reference potential and each of input and output terminals of the oscillation circuit invariable. CONSTITUTION:A varactor diode 26 plays a roll of a parallel capacitance and the oscillating frequency is changed by utilizing property that an inter-terminal capacitance of the varactor diode 26 varies with a change in the control voltage. Since the capacitance of the load capacitor, that is, the capacitance of capacitors 24, 25 giving a large effect on the oscillating condition of the oscillation circuit is unchanged, the oscillating operation is made stable. Thus, the voltage controlled oscillation circuit hardly being unstable is realized, even when the control voltage is changed.
