InGaAs metal-semiconductor-metal photodetectors for long wavelength optical communications
Wissenschaftlicher Artikel
Interdigitated metal-semiconductor-metal (MSM) Schottky barrier photodetectors based on the InCaAs-InP material system have been the subject of keen research over the past couple of years for use in long wavelength ...
Multiple time constant modeling of dispersion dynamics in hetero field-effect transistors
Wissenschaftlicher Artikel
A new approach to the modeling of frequency dispersion effects encountered in the drain current characteristics of state-of-the-art hetero field-effect transistors is presented. The empirical, equivalent-circuit based model ...
Monolithic integration of a folded dipole antenna with a 24-GHz receiver in SiGe HBT technology
Wissenschaftlicher Artikel
The integration of an on-chip folded dipole antenna with a monolithic 24-GHz receiver manufactured in a 0.8-µm SiGe HBT process is presented. A high-resistivity silicon substrate (1000 cm) is used for the implemented circuit ...
A unified approach to charge-conservative capacitance modelling in HEMTs
Wissenschaftlicher Artikel
The voltage dependence of high electron mobility transistor (HEMT) gate-source- and gate-drain-capacitance is described by a set of equations based on a unified charge-conservative model approach. The model is applied to ...
