This article presents a resistorless current-mode first-order allpass filter based on second generation current controlled current conveyors (CCCIIs). The features of the circuit are that: the pole frequency can be electronically controlled via the input bias current: the circuit description is very simple, consisting of 2 CCCIIs and single grounded capacitor, without any external resistors and component...
A current-mode quadrature oscillator using second generation current controlled current conveyors (CCCIIs) as active element is given. The oscillator has high output impedance, employs two grounded capacitors, one electronic resistor and has electronic and independent control on oscillation condition and on oscillation frequency. The proposed circuit is suitable for integrated circuit (IC) architecture...
