摘　　要：针对传统皮尔斯(Pierce)晶振电路功耗较大、启动较慢的问题,设计了一种低功耗快速启动CMOS晶振电路。对传统Pierce电路的反相器结构进行改进,降低了电路功耗;通过引入快速启动电路,明显缩短了晶振的起振时间。理论分析和仿真结果表明,改进的CMOS晶振电路不仅能够快速启动,还大大降低了电路的功耗。To solve the problem of excessive power consumption and long start-up time of Pierce crystal oscillator circuit,a low power and fast start-up crystal oscillator structure was proposed.Inverse amplifier for conventional Pierce circuit was improved to reduce power consumption of the circuit,and start-up circuit was introduced to reduce the start-up time of the crystal oscillator.Both theory analysis and simulation results showed that the improved CMOS crystal oscillator circuit not only started rapidly,but also had a significantly reduced power consumption.
