CURRENT-MODE SINUSOIDAL OSCILLATOR USING CURRENT CONTROLLED CURRENT CONVEYOR TRANSCONDUCTANCE AMPLIFIER

摘要

The realization of current-mode sinusoidal oscillator using current controlled current conveyor transconductance amplifier (CCCCTA) and grounded elements is presented. The simple circuit configuration consists of merely one CCCCTA, one grounded resistor and two grounded capacitors. The use of only grounded capacitors is ideal for integration. The condition of oscillation and the frequency of oscillation can be electronic controled. Moreover, the output current signal can be electronically controllable of the amplitude. The high output impedance of output which facilitates cascading in current-mode configuration. The sensitivities of passive and active elements are low. The simulation results using PSPICE are given for the introduced sinusoidal oscillator to verify the theory and to exhibit the performances of the circuit.
