Abstract

This paper presents a novel impedance multiplier that can be used to scale up a passive element 360 times its original value. The proposed design uses commercially available integrated circuits; an operational transconductance amplifier and second-generation current conveyors (\(\hbox {CCII}\,\pm \)), and a single grounded resistor. By introducing a second OTA, the proposed design can produce a temperature insensitive negative and positive impedance scaler. The functionality of the design was confirmed using PSPICE simulation tool.
