| 摘 要： | 介绍了一种基于低压、宽带、轨对轨、自偏置CMOS第二代电流传输器(CCII)的电流模式积分器电路,能广泛应用于无线通讯、射频等高频模拟电路中。通过采用0.18μm工艺参数,进行Hspice仿真,结果表明:电流传输器电压跟随的线性范围为-1.04～1.15 V,电流跟随的线性范围为-9.02～6.66 mA,iX/iZ的-3 dB带宽为1.6 GHz。输出信号的幅度以20dB/decade的斜率下降,相位在低于3 MHz的频段上保持在90°。

| Abstract: | An integrator based on low-voltage,wideband,rail-to-rail and self-biased CMOS second generation current conveyor(CCII) is proposed,which is widely used in wireless communications,RF and other high-frequency analog circuits.Using 0.18um CMOS process parameters,the Hspice simulation showed that the following voltage of the current conveyor varies linearly from-1.04V to 1.15V,and the linear range of the following current is-9.02mA～6.66mA.The iX/iZ has-3dB bandwidth of 1.6GHz.The output amplitude decreases on the slope of 20dB/decade,and the phase remains 90 degree when the frequency is below 3 MHz. |
