This circuit in Figure 1 produces the amplitude curve illustrated in Figure 2. 2. Wideband Response for Circuit of Figure 1. The voltage gain of the op amp stage itself is 20, but this is cut in half ...

(Editor's additional note: if you are not familiar with the principles and analysis of PID control: you should be; It is the most important, studied, understandable, and applied closed-loop control ...

In a balanced op-amp circuit, the op-amp inputs see equal impedances looking into the circuit. Balanced circuits provide better performance by cancelling some input errors and have a simple R F /R I ...

The ordinary modern IC op amp is fully applicable to most standard amplifier configurations. Error sources are small and may be of no concern, or one can easily ...
