Abstract
This paper presents a low voltage low-power dual output second generation current conveyor (DO-CCII)-based universal filter using carbon nanotube FET (CNTFET) technology. The 3 dB BW for voltage gain and current gain is 54.028 GHz and 48.846 GHz, respectively, for DO-CCII. The average power consumed by the DO-CCII is 440.33 $${\upmu }$$ W. It has a DC voltage range from −370 to 410 mV and a current range from −160 to 160 $$\upmu $$ A. The multi-input single output (MISO) universal filter provides low pass (LP), high pass (HP), bandpass (BP), band reject (BR), and all pass (AP) responses in voltage mode. The filter uses two DO-CCII blocks, two capacitors, and two voltage-controlled resistors, providing resistor behavior. The simulations of all the circuits are performed using HSPICE with a supply voltage of ± 0.5 V. The universal filter operates at 14.79 MHz for controlled voltages of 0.5 V each. The operating frequency can be tuned easily by using the control voltages implementing voltage-controlled resistors. Since the circuit is free from resistors, it can easily be used in analog signal processing ICs for high-frequency applications. The average power consumed by the universal filter is 961.80 $$\upmu $$ W.
