| Summary: | 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. |
