Abstract
A systematic approach to adjust the amplitude of a sinusoidal nonlinear oscillator is discussed in this paper. Operational transconductance amplifier (OTA) and adjustable high-Q, second order bandpass filter are nonlinear element and linear element, respectively. The describing function method is used to find periodic solutions for nonlinear system. Experimental and simulation results are simulated using ORCAD CAPTURE, while, the numerical results are obtained using MAPLE and MATLAB.
