I am only an egg, but I've just ordered this book by Don Lancaster about
active filter design, and the blurb on Amazon says:

"An active filter needs no inductors. Instead, op amps, resistors, and
capacitors are used for better results. Advantages include lower cost,
easy tuning, simple design, and modularity."

It's at <http://www.amazon.com/gp/product/075062986X>.  Comments, anyone?
