A New Electronically Tunable CM/VM Oscillator Using All Grounded Components

With the use of two Voltage Differencing Current Conveyers (VDCC) as active building blocks, and three passive elements, i.e., one resistor and two capacitors, an electronically tunable sinusoidal oscillator has been designed. The proposed configuration offers advantages like low component count, use of grounded elements, and attainment of an independent condition of oscillation (C.O.) and frequency of oscillation (F.O.). Dual-mode operation and efficient integrated circuit implementation due to use of all grounded capacitors improve the performance of the design. The graphical results using PSPICE simulation software, for verifying the functionality of the designed oscillator, have been obtained by employing CMOS structure of VDCC as well as off-the-shelf realization using OPA860.
