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°。
An integrator based on low-vohage,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 0.18urn 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.
