Abstract
In this paper, a new topology for a third order quadrature oscillator (QO) using a new active element, voltage differencing buffered amplifier (VDBA) is proposed. The proposed QO topology is implemented using a meld of lossless and lossy integrators that produce sinusoidal oscillations equally spaced in time with phase shift of 90 degrees. The functionality of the proposed QO is verified with the help of PSPICE simulations using 0.35µm TMSC CMOS technology. The total harmonic distortion (THD) of the proposed QO is observed to be quite low for a wide range of frequencies.
