Abstract

The design of VCO using OTA as active element is discussed in this paper. Several Quadrature oscillator structures ere presented. They use only OTAs and capacitors end are very useful for IC fablication. The frequency of oscillator, $\omega_0$ are proportional to the gm of the OTA and the structures are appropriate for high frequency yea and sinusoidal oscillator operation.
