The sine wave generator composed of inverter is shown as the chart. The circuit could get high stable sine wave in more than a few MHz. In the figure, A1 and the crystal oscillator form a oscillating circuit, the output of A1 becomes sine wave signal after passing the buffer A2. In the circuit, A1 is linear amplifier, the whole circuit is in amplifying state. As the characteristics of the crystal oscillator are different, the output frequency and voltage are different, and R2 is used to adjust waveform. For getting ccurate oscillation frequency, it can connect a variable capacitor on two ports of capacitor C1 in parallel. Oscillation frequency of the circuit is decided by crystal oscillator, it can change the output signal frequency.
