Example 3—AC and Noise Analysis of a Band<br />

Pass Filter<br />

Netlist file: ac_noise_filter.cir<br />

This example deals with a typical PCB example of a simple opamp band pass active filter using<br />

opamp macromodels. The simulation performs an AC analysis of the circuit, together with a<br />

noise analysis, of the output stage of the filter to obtain the small-signal frequency and noise<br />

responses respectively.<br />
