Abstract :
The paper discusses phase locked loop (PLL) and magnitude locked loop (MLL) techniques based on voltage controlled filter (VCF), for the automatic frequency control (AFC) of active filters. Applications to a microwave planar filter are considered. Theoretical analysis, simulated and measured results are presented for both phase and magnitude control circuits enabling the filter to accurately track a reference signal
