WebIn Part 1 (Reference 1), the closed-loop transfer function of the non-inverting op amp configuration in the frequency domain was calculated. Specifically, the transfer function was derived with the assumption that the op amp had a first-order open-loop response. For calculating gain error, the magnitude response is of interest. For convenience, Webcapacitor, C2, introduces a zero in the noise gain transfer function, which stabilizes the circuit. Notice that in Fig. 3 the closed-loop bandwidth, fcl, is the frequency at which the noise gain intersects the open-loop gain. The Bode plot of the noise gain is a very useful tool in analyzing op amp stability.
