“…Since then, many current-mode circuits based on CCCII, like the analog filters, oscillators, and gyrator circuits, have been investigated, which shows that the CCCII is a very interesting current-mode device. In spite of the fact that oscillators using CCCIIs have been widely reported [6][7][8][9][10][11][12][13][14] , they are neither Wien-bridge oscillators, nor oscillators with orthogonal adjustment between the resonant frequency and resonant condition. Literature survey shows the CCCII scillators using the traditional Wienbridge oscillator rather than the grounded-capacitor Wien-bridge oscillator as topology have rarely been reported so far.…”

This paper designs a current-mode Wien-bridge oscillator to use current-controlled conveyor (CCCIIs) based on the traditional Wien-bridge oscillator and the adjoint network theorem. This oscillator employs only four CCCIIs and two grounded capacitors. Its resonant condition and resonant frequency can be independently and electronically varied by tuning bias currents of the CCCIIs linearly. Then this oscillator is simple in design, compact in size, and convenient in adjustment. The oscillator analysis and computer simulation results have been included to support the generation method.
