Abstract
A current controlled operational transconductance amplifier based sinusoidal oscillator circuit that provides oscillation based on the transconductance and parasitic capacitance of the operational transconductance amplifier without externally connected capacitances. The oscillation frequency is adjusted through a variable current source or a variable resistor with a DC voltage source.
