Voltage-controlled oscillator having voltage-sensitive capacitor with bias supply circuit |
摘要 |
An impedance adjustment capacitor connected in parallel to a choke coil formed by a conductive pattern formed on a substrate adjusts the impedance of a control voltage applying circuit. A control voltage is applied via the choke coil to a variable capacitance diode included in a resonance circuit. This control voltage determines a resonance frequency. |
