Design, optimise and simulate an active filter within minutes
You are on a quest to design an active filter. You have the specifications of the filter’s frequency response, but how do you create a circuit that does just what you want? If you took the conventional approach, you would need to manipulate the second-order control system equations by consulting multiple filter-response coefficient tables.
Then you would plot and compare multiple filter responses; select the filter response that best meets your specification; choose a circuit topology and calculate the passive component values by solving complex quadratic equations; and pick standard, graded passive components and an operational amplifier (op amp) that closely match the calculated values.
You’ll need to repeat component selection and calculations until you achieve the desired performance, a process that could easily take weeks, if not months.
TI’s Filter Design Tool streamlines the system design, circuit design and circuit verification process and helps you select a filter circuit that has high chance for first-pass success.
