Voltage controlled oscillator with linear capacitance

摘要

The oscillator has an amplifier (5), and an oscillating network (6) with an inductor (L) and variable capacitors (Cv+, Cv-). The capacitors are connected in series between a feedback terminal (7) and ground. The capacitor (Cv+) has its capacitance varying in direction same as that of a control voltage and the capacitor (Cv-) has its capacitance varying in direction opposite to that of the control voltage.
