Analog Simulation - Active Filters

These active filter circuit examples use cascaded amplifier stages that are configured for first- or second-order filter sections. The filter amplifiers operate in a single-supply configuration, and the example circuit includes a Vs/2 buffer for common-mode biasing where necessary. While the circuits feature the MCP6001, a general purpose, 1MHz opamp, the user can easily modify the circuit by replacing the MCP6001 with other available opamp models included in the library.
