Current-Mode Four-Phase Quadrature Oscillator By Means Of Current Differencing Transconductance Amplifier
Nidhi Pant,  Vishal Ramola
In this document, a CMOS current-mode four-phase quadrature oscillator by means of current differencing transconductance amplifier (CDTA) that is based upon the pioneering first-order allpass filter is projected. The anticipated circuit configuration defines a very simple structure. It contains simply one resistor, two capacitors and three CDTAs. It is capable of affording four quadrature current outputs, and the stable affirm oscillation is also achieved subsequently to fewer than 1μs. Additionally, as the entire output impedances of the four-phase quadrature oscillator are high, the proposed oscillator circuit can be connected directly to the subsequent stage without any impedance identical necessities. PSPICE simulation results are included to substantiate the supposition.
