Voltage-controlled oscillator circuit has LC resonator, damping correction amplifier coupled to resonator, voltage-controlled capacitor with control connection connected to supply voltage

摘要

The device has an LC resonator with an inductance and a first voltage-controlled capacitance (1) for setting an oscillation frequency, a damping correction amplifier for providing a negative impedance coupled to the resonator, a supply voltage connection (Vcc) coupled to the amplifier and a second voltage-controlled capacitor (2) in parallel with the first with a control connection (4) connected to the supply voltage connection.
