We can combine two of the above examples to demonstrate implementing a third order high-pass function distributed across a larger circuit. Figure 12 is a diagram of a third-order high-pass function ...

Low-pass filter (LPF) provides a constant output from DC up to a cutoff frequency f(H) and rejects all signals above that frequency. Circuit diagram shown below is a first-order low-pass Butterworth ...

Also, the composite buffer in Figure 2 completely eliminates power-dissipation-related errors in the op-amp input.1 C9 and C10 can be replaced by adjustable shunt regulators and R3 and R4 by ...
