a complete procedure for the design of w-band low noise amplifier in mmic technology is presented. the design is based on a simultaneously power and noise matched technique. for implementing the method, scalable bilateral transistor model parameters should be first extracted. the model is also used for transmission line utilized in the amplifier circuit. in the presented method, input/output ma...

There is a huge development in mobile communications in Europe and consequently, the need for training engineering students in microwave design is growing. We present here some students projects aimed at designing microwave subsystems in MMIC and HMIC technology, for different wireless communications applications. They have been performed at LHOG/ENSERG (INPG), France. The capabilities and cons...

In this project a number of circuits [1-4] with the characteristics of a passive inductor are to be assessed for their suitability for implementation in MMIC applications as a means of introducing a tuning function and as a replacement for the conventional passive inductor.

We have studied the reliability of intrinsic SiN MIM capacitors designed for 48 V and 125 0 C operation and manufactured in a GaN process flow. It is shown that very small area capacitors (10um x 10um) with a dielectric thickness of 400nm exhibit lifetimes as long as 1.48E10 hours under such conditions.

Recently there is significantly increasing interest in the development of THz devices and circuits. Different from the MMIC device and circuit technologies, THz devices approach to the electrical limit of semiconductors and passive THz circuit elements have much less dimension tolerance. Therefore, device and circuit technologies concerning to such limitations have to be reconsidered and modifi...

Backside via self-inductance is a critical electrical quantity needed for the design of Monolithic Millimeter-wave Integrated Circuits (MMIC). We have investigated a simple, analytical method for accurately calculating via inductance based upon physical geometry. The analytical method enables backside via process development to be tailored to meet design goals. Conversely, the sensitivity of RF...
