Abstract:

 

The realization of 2 current-mode quadrature oscillators  using current-controlled current differencing transconductance  amplifiers (CCCDTAs) and grounded capacitors is presented.  The  proposed oscillators can provide 2 sinusoidal output currents with a  90° phase difference.  They enable noninteractive dual-current control  for both the condition of oscillation and the frequency ofi  oscillation.  The high-output impedances of the configurations enable  the circuit to be cascaded without additional current buffers.  The  use of only grounded capacitors is ideal for integration.  The circuit  performances are depicted through PSpice simulations; they show good  agreement to theoretical anticipation.
