The paper considers transition from sinusoidal to relaxation oscillations in the RLC-oscillator the frequency of which is tuned by the resonator capacitance. The active element of this oscillator is a transconductance amplifier with limited output current. When the tuning capacitor is large the oscillations are nearly sinusoidal. Diminishing the tuning capacitor value one moves smoothly from sinusoidal to relaxation oscillations, and when this capacitor is reduced to zero value the oscillator… CONTINUE READING
