Signal Up-conversion for Integrated Radar Systems

Frequency up-conversion is an integral part of the (sub)mm wave integrated radar system that is currently developed at the TUDelft in the context of the MEMPIS program. The proposed up-converter IC allows the necessary signal modulation for the radar to be generated at a relative low frequency, after up-conversion to W-band takes place. In our...

Analysis and Design of a Multi-Core Oscillator for Ultra-Low Phase Noise

In this paper, we exploit an idea of coupling multiple oscillators to reduce phase noise (PN) to beyond the limit of what has been practically achievable so far in a bulk CMOS technology. We then apply it to demonstrate for the first time an RF oscillator that meets the most stringent PN requirements of cellular basestation receivers while...

MMIC packaging using Flip-Chip technology at G band

Front-end Monolithic Microwave Integrated Circuits (MMICs) have recently become commercially available for frequencies above 100 GHz. However, achieving low-loss and broadband interconnections between the antenna and MMICs is challenging for integrated front ends at these frequencies. This thesis presents the characterization of a flip-chip...
