VOLTAGE CONTROLLED OSCILLATOR WITH IMPROVED VOLTAGE VERSUS FREQUENCY CHARACTERISTIC

摘要

An undesirable relationship between user applied input frequency control voltage and output frequency of a voltage controlled oscillator is counteracted by controlling the characteristics of an amplifier stage in the oscillator as a function of frequency control signal in addition to controlling the output frequency of the oscillator as a function of the capacitance of a user controlled variable capacitance in response to the frequency control signal.
