High-Gain and High-Efficiency EER/Polar Transmitters Using Injection-Locked Oscillators

Phase - Locked Loops for High - Frequency Receivers and Transmitters – Part

In this second part, we will focus on a detailed examination of two critical specifications associated with PLLs: phase noise and reference spurs. What causes them and how can they be minimized? The discussion will include measurement techniques and the effect of these errors on system performance. We will also consider output leakage current, with an example showing its significance in openloo...

High-Efficiency Power Amplification Techniques for Wireless Transmitters

The low efficiency of existing power amplifiers (PAs) is causing excessive energy consumption in wireless systems. Improving the PA efficiency is therefore of great environmental and economical importance. This thesis address a wide range of advanced PA design methods and novel PA architectures that all contribute to significantly improve the efficiency of PAs for wireless applications. The fir...

SWITCHED-MODE MICROWAVE CIRCUITS FOR HIGH-EFFICIENCY TRANSMITTERS by MANOJA

Date The final copy of this thesis has been examined by the signatories; and we find that both the content and the form meet acceptable presentation standards of scholarly work in the above mentioned discipline iii Thesis directed by Professor Zoya Popovi´c In wireless communications systems, the transmit front-end consumes a large fraction of the total available power. In particular, the power...
