Journal ArticleDOI
Class E-A new class of high-efficiency tuned single-ended switching power amplifiers
Nathan O. Sokal,Alan D. Sokal +1 more
TL;DR: In this article, a load network is synthesized to have a transient response which maximizes power efficiency even if the active device switching times are substantial fractions of the a.c. cycle.
Journal ArticleDOI
Power amplifiers and transmitters for RF and microwave
Frederick H. Raab,Peter M. Asbeck,Steve Cripps,Peter B. Kenington,Zoya Popovic,Nick Pothecary,John F. Sevic,Nathan O. Sokal +7 more
TL;DR: In this article, a wide variety of techniques, implementations, and active devices are presented to generate RF/microwave power for wireless communications, but also in applications such as jamming, imaging, RF heating, and miniature dc/dc converters.
Class of High-Efficiency Tuned Switching Power Amplifiers
Nathan O. Sokal,Alan D. Sokal +1 more
TL;DR: Advantages of Class E are unusually high efficiency, a priori designability, large reduction in second-breakdown stress, low sensitivityy to activedevice characteristics, and potential for high-efficiency operation at higher frequencies than pI eviously published Class-D circuits.

Amplifying and processing apparatus for modulated carrier signals
Alan D. Sokal,Nathan O. Sokal +1 more
TL;DR: In this article, the amplitude and phase transfer functions of a power amplifying and signal processing system for modulated carrier signals are controlled by a nonlinear function generator which acts upon the signal fed by that path to the comparator.
Journal ArticleDOI
Near-Optimum Dynamic Regulation of DC-DC Converters Using Feed-Forward of Output Current and Input Voltage with Current-Mode Control
Richard Redl,Nathan O. Sokal +1 more
TL;DR: In this article, the authors proposed to add feed-forward of output current and input voltage to a current-mode controller, which is applicable to both forward and flyback types of converters and to all types of currentmode control.
