Effects of Non-Idealities of OP-AMPs on Active Filters: An Analytical Study
This paper studies the effect of non-idealities of OP AMPs on the performance of active filters. The non-ideality is considered in terms of finite gain, finite gain-bandwidth product, slew-rate, and offset voltages. The effect of these non-idealities on active RC & switched capacitor filters is...

Summary: | This paper studies the effect of non-idealities of OP AMPs on the performance of active filters. The non-ideality is considered in terms of finite gain, finite gain-bandwidth product, slew-rate, and offset voltages. The effect of these non-idealities on active RC & switched capacitor filters is highlighted. Some ways of reduction of these effects are also suggested and relative advantages and disadvantages of various compensation techniques are discussed. |
