Abstract
Bhattacharyya and Natarajan have established the condition for oscillation of a three operational amplifier (OA) active-R oscillator. This letter shows that the integrator model used by them is incorrect. Analysis, based on single pole model, indicates the absence of oscillations. However, conditions for oscillations exist when a two pole model of the OA´s is taken.
