170-GHz Power Amplifier in 0.13-μm SiGe BiCMOS

In recent years, the demand for the wireless connectivity is increasing and leads to the research into the above 100GHz design. Developments have been made with the circuit and technologies to make the circuit operate at 100GHz. The current availability of silicon-based technologies providing devices with ft/fmax frequencies exceeding 300-GHz...

A THz Lens Antenna fed by a Photoconductive Connected Dipole Array

Photoconductive antennas have been used extensively for THz radiation the last few years. In this thesis, we propose a photoconductive connected dipole array consisting of 36x36 elements that is used as a feed in a THz silicon lens and radiates in a band ranging from 100 GHz to 5 THz. Specifically, we compute theoretically the radiated field...
