Novel Single Resistor Controlled Quadrature Oscillator Using Two CDBAs
Sudhanshu Maheshwari and Iqbal A. Khan
In this paper, a single resistor controlled oscillator (SRCO) with quadrature outputs using a relatively new active element, current differencing buffered amplifier (CDBA) is also proposed. The proposed circuit enjoys independent control of frequency and condition of oscillation. SPICE simulation results are also given to validate the proposed oscillator circuit.
