"How High-Frequency PLL Circuits Work and How to Design Them: From Understanding Basic Operation to Low-Noise Techniques" Hiroshi Komiya Price: ¥2800 Content Description PLL (Phase Locked Loop) technology has rapidly become widespread as a frequency synthesizer and is being applied in various fields. Accordingly, higher performance is required of PLLs, and designs that meet the application are necessary. In order to grasp the design technology, this book designs a PLL frequency synthesizer while confirming the operation of the circuits that make up the PLL without using dedicated ICs. This book is packed with hints for improving PLL performance. #HiroshiKomiya #Hiroshi_Komiya #book #electricity/machinery/electronic communication
