The next-generation 5G and beyond-5G wireless systems have stimulated a substantial
growth in research, development, and deployment of mm-Wave electronic systems and …

Modern mobile communication signals require power amplifiers able to maintain very high
efficiency in a wide range of output power levels, which is a major issue for classical power …

This paper presents a wideband 2× 13-bit in-phase/quadrature-phase (I/Q) RF digital-to-
analog converter-based all-digital modulator realized in 65-nm CMOS. The isolation …

Signals designed for high-capacity communications result in high peak-to-average ratio
(PAR) waveforms that the transmitter power amplifier (PA) must amplify with low distortion …

<? Pub Dtl=""?> This paper presents a linear multi-harmonic analysis method to evaluate the
performance of digitally controlled dual RF-input power amplifiers (PAs). The method …

Performing RF amplification in a way that is simultaneously linear and efficient has long
been a challenge in power amplifier (PA) design. In short, single-transistor PAs can either be …

This work discusses the efficiency bandwidth constrains in Doherty amplifiers. An analysis of
the bandwidth limitations imposed by the impedance inverter and output capacitance of the …

Sex differences in physical activity (PA) through pubertal maturation and the growth spurt
are often attributed to changing interests. The contribution of sex differences in biological …

This paper presents a packaged 28-GHz Chireix outphasing transmitter (TX) for power
amplifier (PA) efficiency enhancement at both peak and back-off output power (PBO). The …

In this paper, a generic combiner design technique is developed for class-E outphasing
transmitters. The design procedure starts with calculation of the combiner network …
