Low Pass Filter and High Pass Filter Using CCII

Abstract

The Current conveyors are unity-gain active building blocks that offer exceptionally high linearity and a wide dynamic, which makes them ideally suited for modern analog signal-processing applications where precision and bandwidth are critical [1]. They operate on low supply voltage and consume less power, which makes them suitable for integrated and low-power systems [1].  They posses high input impedance, low output impedance, high CMRR and fast slew rate, enabling efficient and accurate signal processing [1].  Today various current conveyors are available as ICs built using both BJT and MOS technologies, giving designers flexibility for different performance needs. This paper explains and demonstrates the implementation of low-pass and high-pass filters using AD844 IC. It also highlights the optimized scalability and superior performance achieved. The authors have simulated above configuration using CMOS technology and the results are also tabulated for comparison.
