Performance Evaluation of Electronically Tunable Filter Using CCCII in 45nm CMOS Technology for Wi-Fi Applications

Second generation Current Controlled Current conveyors are getting compelling recognition due to their AC performances with better linearity, high sensitivity, wider and nearly constant bandwidth, high slew rate, reduced supply voltage (nearly 0.5V), less chip area and larger dynamic range. CCCIIs are electronically tunable i. e. its parasitic resistance at current input port can be adjusted by an input bias current making it useful for wide range of applications. This paper presents an approach of designing a universal filter using CCCII as its active building block. Filter has been tuned for Wi-Fi applications and realised in 45nm CMOS technology while performances were examined through HSPICE simulations.
