CC-CCTA-Based Current-mode Quadrature Oscillator

  title={CC-CCTA-Based Current-mode Quadrature Oscillator},
  author={Nitiphat Pisutthipong and Phamorn Silapan and Montree Siripruchyanun},
This article presents a current-mode quadrature oscillator using current controlled current conveyor transconductance amplifiers (CC-CCTAs) as active elements. The proposed circuit is realized from a lossy integrator and a lossy differentiator. The oscillation condition and oscillation frequency can be electronically controlled via input bias currents. The proposed oscillator can be applied to provide AM/ASK signals with the above major advantages. The circuit description is very simple… CONTINUE READING
