| Abstract: | This paper introduced the structure and main parameters of quartz crystal oscillator, matching design of load capacitance, calculation of circuitous resistance and crystal dirive power. However, some issues will happen to crystal oscillator if the resonance impedance mismatches oscillation circuit, such as oscillation start-up failure and large frequency deviation. Based on the application of power monitoring module in marine circuit breaker, this paper optimized the design of the crystal oscillator circuit. |
