Abstract :
Novel differential-output quadrature oscillator employing two FB-VDBAs (Fully Balanced - Voltage Differencing Buffered Amplifiers) which are proposed for applications with fully differential architecture is described. This circuit can be also utilized as multi-phase oscillator with four independent single-ended outputs. Detailed analysis of real effects is included and its comparison with the results of experimental measurements is accomplished.
