CNFET-based digitally controlled impedance multiplier

In this paper, a carbon nanotube-FET based impedance multiplier is presented. The circuit uses digitally controlled inverting current conveyor (DCICC). Proposed circuit is functioning accurately with a multiplication factor from 0 to 7. The technique is simple, versatile and compatible for microelectronics. The proposed circuit uses only one active element along with a grounded capacitor. The tuning of impedance is based on the number of tubes in a CNFET with switched on condition which is selected by a digital control technique. The circuit operates with low supply voltage of 0.7 V. The results of DCICC have been verified through HSPICE simulation. © 2021, Bharati Vidyapeeth's Institute of Computer Applications and Management.
