A C-Band Monolithic Silicon-Bipolar Low-Power Low-IF WLAN Receiver (2008)
Corrado Carta, Martin Schmatz, Rolf Vogt, Werner Bächtold
Abstract — This paper presents the design, implementation and measurements of a monolithic low-IF receiver compliant with the main 5 GHz WLAN standards. It consists of a low-noise preamplifier,...
One-Step Patterning of Asymmetric Gate Recess for InP HEMTs using Genetic Algorithms (2008)
Franck Robin, Andrea Orzati, Esteban Moreno, Michael Spühler, Otte Homan, Werner Bächtold
For the first time, a canonical genetic algorithm was used to optimize the resist profiles for T-gate fabrication. An e-beam lithography simulation tool was elaborated that calculates the...
A Two Stage, Monolithic Integrated 200 mW HEMT Amplifier for Wireless ATM (2007)
Thomas A. Bös, Urs Lott, Werner Bächtold
For wireless LAN applications a compact two stage HEMT amplifier is designed and on-wafer measured with on-chip matching and bias networks. At 17.2 GHz the amplifier delivers 23.1 dBm saturated...
