摘要 提出了一种基于电荷泵的模拟开关结构。该结构使用电荷泵抬升MOS管的栅电压,从而大大改善开关的导通能力、线性度和动态传输范围。通过仿真验证了开关电路性能,结果表明设计的开关电路在电压0-5V范围内,导通电阻很小且信号损耗很小无失真。因而特别适用于低压系统。 This paper put forward an analog switch structure based on charge pump.It upraises the gate voltage of the MOSFET,thereby greatly improve the switch conduction ability,linearity and dynamic transmission range.The simulation results show the switch circuit performance.In voltage 0~5V range,conduction resistance and signal losses are very small.This circuit is especially suitable for low voltage system.
