Electronically tunable capacitance multiplier and frequency-dependent negative-resistance simulator using the current-controlled current conveyor

Electronically tunable capacitance multipliers and a frequency-dependent negative-resistance (FDNR) are presented in this article. The multiplying factors of the capacitance multipliers and the value of the FDNR are tunable by adjusting the bias current of a plus-type current-controlled current-conveyor (CCCII+). The feasibility of obtaining temperature-independent capacitance multiplication factors is explored and the SPICE simulation results included.
