Abstract :
A simple method is proposed for estimating the ratio of the second pole to the gain-bandwidth product of matched operational amplifiers (OAs). This ratio is an important parameter in deciding the stability of composite OA-based circuits. The theoretical analysis of the method is presented, and experimental results are given
