A Novel Voltage-Control Sinusoidal Oscillator using Operational Transconductance Amplifier

Abstract
In this research, we intend to develop a sinusoidal VCO with low harmonic distortion.
A new sinusoidal VCO is developed with only two OTAs. The number of OTAs is fewer than that previously presented in other papers. The oscillator will be
easy to debug and the complexity of the oscillator can be reduced.
An AGC control mechanism is applied to the VCO to control the oscillation amplitude and to reduce the harmonic distortion.
The oscillation is designed with the frequency around 100MHz and the oscillation amplitude is around 100mV. The simulation results and the problem encountered are discussed.
