This chapter presents a variety of voltage-controlled impedance realizations most of which, apart from dealing with voltage-controlled resistances, also deal with voltage-controlled capacitances, voltage-controlled, inductances and voltagecontrolled frequency-dependent negative resistance. Such voltage-controlled, impedances have been realized so far using a variety of active integrated circuit building blocks such as operational amplifiers, operational transconductance amplifiers, second-generation current conveyors and current feedback operational amplifiers. Various configurations for realizing grounded/floating, positive/ negative voltage-controlled impedance circuits have been detailed out, and some of their representative applications have been illustrated.
