As shown in the figure is a sinusoid generator circuit composed of inverter.This circuit can get high stable sine waves above several MHZ. A1 and crystal oscillator in the figure consist a oscillating circuit . The output of A1 will export sine wave signals after passing through buffer A2. In the circuit, A1 is a linear amplifier,and the whole circuit work in a state of amplification. Due to the different characteristics of the crystal oscillators being used, output frequency and voltage of the circuit are different. R2 can be used to adjust waveform. In order to obtain accurate oscillation frequency,you can have a fine adjustment by connecting semi-variable capacitors in parallel between the ends of capacitance C1 . The oscillation frequency of circuit is determined by crystal oscillators. Change of crystal oscillators will bring out alterations in output signal frequency.
