Electronically Tunable Sinusoidal Oscillator Using Only Single Current-Controlled Current Conveyor Trans-Conductance Amplifier

Abstract

This work presents a wide frequency range sinusoidal oscillator design that relies on only one active component, a current-controlled current conveyor trans-conductance amplifier, and a few passive components. It just employs two grounded and non-floating capacitors and one resistor to complete the procedure. This design has the advantage of allowing the oscillation frequency and condition to be adjusted not only electronically, but also separately, without affecting the values of any passive components. To verify the functionality and usefulness of the developed sinusoidal oscillator circuit, ORCAD PSPICE simulations are done using 0.18 um process parameters for complementary metal oxide semiconductor technology. The obtained results demonstrate its application to a wide range of frequency generation without the need for additional components, hence validating the theoretical expectation.
