Sinusoidal oscillators with explicit current output employing current-feedback op-amps

摘要

Employing a state-variable synthesis, a number of new current-mode oscillators with explicit current output have been derived, which can be practically implemented from commercially available current-feedback op-amps (CFOA). The workability of the proposed structures has been confirmed by experimental results using AD844-type CFOAs and some sample results have been presented.
