Design of a Crystal Oscillator Circuit

The theoretical analysis of the crystal oscillator circuit of frequency source is introduced in this paper. And an ADS simulation model is built to verify the impact of the impedance variation at the output end of the crystal oscillator circuit on the output power of the 100MHz clock signal. And a scheme to increase the reverse isolation of the clock circuit is proposed. Besides, the influence of temperature on the shape variable of crystal circuit board is analyzed, and the best thickness of the crystal oscillator circuit board is optimized.
