摘　　要：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.
