Analog frontends for optical communications up to 80 GBit/s

Más información sobre el libro

This book studies methods of enhancing both data rates and power efficiencies of analog frontends for high-speed optical communication systems. Performance measures for highspeed broadband circuits and the efficiency of frequency compensation methods are evaluated. Power-efficient speed enhancement such as inductive peaking, feedback and Negative Miller Capacitances, as well as the method of inductive broadband output matching are analyzed in detail. New methods for the design of power-efficient high-speed broadband amplifiers are developed. Circuit design examples intended for use in 40 GBit/s to 80 GBit/s short-range optical communication systems at 850 nm wavelength demonstrate the efficiency of the presented methods.
