Abstract


This article presents a DO-CCCFTAs-based current-mode Quadrature Oscillator (QO). Along with the sinusoidal quadrature signal, the proposed circuit also has output signals that can adjust the amplitude and the Oscillation Frequency (OF) can non-interactively control the Oscillation Condition (OC). The circuit's impedances with high output can directly drive the load without using a current buffer. In addition, grounded capacitors can work without needing any external resistors and not extended output ports of the active device. This qualification is very appropriate for being developed in the future for an integrated circuit. The simulation results obtained from PSpice and experiment by commercial integrated circuit correspond with the theoretical analysis.
