Description :
This paper discusses the realization of OTA based current
-
mode quadrature oscillator circuits
based on third
-
order integrator based
Continuous
-
Time (CT) filter structures. These quadrature oscillator
circuits use three/ five OTAs and three grounded capacitors. The advantages of proposed quadrature
oscillator circuits include simple architecture, use of grounded capacitors, independent
control on
Condition of Oscillation (CO) and good sensitivity of Frequency of Oscillation (FO). The workability of the
proposed oscillators is verified with SPICE simulations.
