Design of Low-power Low-frequency and Fast Start-up Circuit

  • 摘要: 为了解决传统皮尔斯结构互补氧化金属半导体(CMOS)晶振电路功耗过大的问题,设计了一种集成在专用无磁计量芯片内的低频起振电路,其振荡频率为32.768 kHz.在传统皮尔斯结构晶振电路的基础上,设计了改进型推拉式晶振电路,有效地降低了功耗,并能实现快速起振.采用Chartered的0.35μm工艺模型进行设计、仿真和流片.测试结果表明,电路工作正常,稳定后平均工作电流仅为0.39μA,起振时间小于200 ms,满足了系统对频率及功耗的要求.
    Abstract: To overcome the limitation of large power in the complementary metal-oxide semiconductor (CMOS) crystal oscillator circuit of traditional Pierce structure,this paper designed a kind of low-frequency start-up oscillator circuit,which was integrated into the specific non-magnetic meter chip and its frequency was 32.768 kHz.By using the improved push-pull crystal oscillator circuit,the designed circuit could reduce the power effectively and start up quickly.The circuit design,simulation and tapeout had been completed by adopting the Chartered 0.35 μm process model.Test results show that the circuit works correctly,the average operating current is 0.39 μA after stabilization,and the start-up time is less than 200 ms,which meet the system's requirements of frequency and power.
