N2 - The influence of the finite gain—bandwidth product of operational amplifiers on the performance of state-space SC circuits is summarized. A new method is then presented which eliminates the amplifier finite-gain effect completely. This makes it possible to use high-speed single-stage amplifiers with moderate gain values (e.g., as low as 100), for precise high-Q filtering applications. In this way, it becomes feasible to design SC circuits for signal frequencies up to 1 MHz.
