A Floating Capacitance Multiplier based on Current Conveyors

Abstract

A floating capacitance multiplier based on current conveyors is introduced. The circuit employs twosingle output current conveyors one multiple output current conveyor two resistors and one grounded capacitor.The floating capacitance multiplier can be used to modify the value of common capacitor by using multiplicationfactor as a key to modify. The multiplication factor results from operation of circuit can be tuned to obtain thevalue more or less than 1 depend on ratio of two resistors. Moreover, the circuit can be modify to achieve thecurrent control multiplication factor which have an attractive feature for many application. SPICE simulationsshow that the proposed capacitance multiplier can be operated with wide frequency range.
