Abstract
A completely tunable second order low-pass filter with minimal active circuitry is disclosed. The filter provides a very flexible choice of filter parameters such as cutoff frequency, DC gain, and Q factor, by selecting appropriate resistor values for a single integrated circuit with much lower capacitance, capacitance ratio, and active circuitry than other standard low-pass circuit configurations.
