CURRENT MODE QUADRATURE OSCILLATOR CIRCUIT DESIGN USING MCBTA ACTIVE COMPONENT

Abstract

In this study, a new current-mode
quadrature sinusoidal oscillator circuit using modified current backward
transconductance amplifier (MCBTA) are introduced. A new quadrature sinusoidal oscillator
circuit employs two MCBTAs, two grounded capacitors and one grounded resistor.
The current outputs of the proposed circuit provide high-frequency sinusoidal
oscillation in quadrature at high impedance current output terminals of the
MCBTAs. The oscillation condition of the proposed quadrature oscillator is
controlled by one resistor and/or (g_m)
transconductance value of MCBTAs. The validity of the proposed circuits is
verified PSPICE simulations. CMOS implementation of the MCBTA is performed for
TSMC 0.25 µm process parameters and simulation results are obtained.
