Abstract :
Some new RC-oscillator configurations using the second generation current conveyor (CC II) and unity-gain voltage-follower active elements are reported. The circuits are novel because they use only the minimum passive-RC components, single grounded resistor tunability and extremely low active and passive ω0-sensitivities. A comparative study on voltage-follower block implementation with the usual op-amp and the relatively newer CC II element, along with their sensitivity characteristics, has also been included.
