CMOS CCII– based on modified dual output-OTA for high frequency applications

A negative CMOS second generation current conveyor (CMOS CCII–) based on modified dual output CMOS folded cascode operational transconductance amplifier (CMOS DO-OTA) is presented. The proposed folded cascode CMOS DO-OTA with attractive features for high frequency operation such as high output impedance, wide bandwidth, high slew rate, with low power consumption is used in the realisation. The proposed CMOS DO-OTA and CMOS CCII– with high performance parameters can be used in many high frequency applications. The proposed CMOS CCII– achieves 1.37 GHz (−3 dB BW), 1.8 ns settling time, 48 V/μs slew rate, and low power consumption around 3.25 mW for ±2.5 V supply. P-Spice simulation results are included for 0.5 μm MIETEC CMOS technology.
