The ever increasing demand for high data rates in wireless communication systems is pushing systems to utilize more and wider bands available at higher frequencies. As modern downscaled CMOS technology offers a high level of integration and low cost in mass production, a substantial research effort has been put on designing also mm-wave CMOS circuits in recent years. The overall aim of the project is to investigate circuit techniques, in oscillators, mixers and power amplifiers, for implementing a high efficiency mm-wave transmitter in CMOS technology. High efficiency is specifically important for battery powered devices. The power amplifier is one of the most crucial blocks for the communication distance and power consumption of a wireless transceiver. It is therefore also the circuit block that mainly determines the overall efficiency. Building a solid understanding of the transmitter blocks is here crucial to be able to advance the state-of-the-art by improving the performance with novel architectures and circuit level techniques.
