Floyd M Gardner

Floyd M. Gardner is well-known expert and author in the area of PLL's. The first, second, and third editions of his book Phaselock Techniques have been highly influential and remains a well-recognized reference among electrical engineers specializing in areas involving PLL's.

Moreover, he has written a remarkable IEEE paper dedicated to the description, the modelling and the characterization of the widely used Charge-Pump Phase-Lock Loops (see references below). This paper constitutes a major turorial for scientists and designers who want to discover this very widely used mixed-signal system.
