Abstract

This paper proposes a new single resistance
controlled sinusoidal oscillator (SRCO) which employs only one
voltage differencing current conveyor (VDCC), two grounded
resistors and two grounded capacitors. The presented circuit
configuration offers the following advantageous features (i)
explicit current-mode output with independent control of
condition of oscillation (CO) and frequency of oscillation (FO) (ii)
low active and passive sensitivities and (iii) a very good frequency
stability. The proposed structure can also be configured as (a)
trans-admittance low pass filter and band pass filter and (b)
quadrature oscillator. The validity of the proposed SRCO,
quadrature oscillator and trans-admittance low pass filter and
band pass filter has been verified by PSPICE simulations using
TSMC CMOS 0.18μm process model parameters.
