Current-Mode Third-Order Quadrature Oscillator Using CDTAs

open access: yesActive and Passive Electronic Components, 2009
This paper describes a current-mode third-order quadrature oscillator based on current differencing transconductance amplifiers (CDTAs). Outputs of two current-mode sinusoids with 90° phase difference are available in the quadrature oscillator circuit ...

Nonlinear optical tomography of q-deformed entangled pair coherent states

open access: yesResults in Physics, 2021
We introduce entangled pair coherent states of a noncommutative harmonic oscillator operators associated with a q-deformed oscillator algebra. The definition of two-mode q-deformed operator and the decomposition of its eigenstates in terms of the q ...
