Abstract
A simple frequency tuning circuit based on a peak-detection scheme is designed to tune a fifth-order Chebyshev lowpass filter based on the inverse-follow-the-leader feedback (IFLF) topology. The tuning block consists of very simple circuitry. Simulated and measured results verify the tuning function
