A DC~1.6GHz DISTRIBUTEDAMPLIFIERWITHGaAs MESFETs

open access: yes, 2016
In this study, a DC ~ 1.6 GHz bandwidth distributed amplifier (DA) is fabricated in printed circuit board (PCB). The scattering (S-) parameters of the distributed amplifier are measured and compared with simulated results. In characterization of the amplifier, small-signal microwave Sparameters given at some discrete frequencies of transistors are ...

Theory Based on Device Current Clipping to Explain and Predict Performance Including Distortion of Power Amplifiers for Wireless Communication Systems [PDF]

open access: yes, 2008
Power amplifiers are critical components in wireless communication systems that need to have high efficiency, in order to conserve battery life and minimise heat generation, and at the same time low distortion, in order to prevent increase of bit ...

GaAs optoelectronic neuron arrays [PDF]

open access: yes, 1993
A simple optoelectronic circuit integrated monolithically in GaAs to implement sigmoidal neuron responses is presented. The circuit integrates a light-emitting diode with one or two transistors and one or two photodetectors. The design considerations for

Investigation into intermodulation distortion in HEMTs using a quasi-2-D physical model [PDF]

open access: yes, 2001
The need for both linear and efficient pseudomorphic high electron-mobility transistors (pHEMTs) for modern wireless handsets necessitates a thorough understanding of the origins of intermodulation distortion at the device level.

Analytical Solution to the Gradual Channel Approximation for Metal–Oxide‐Semiconductor Field‐Effect Transistors

open access: yesphysica status solidi (b), EarlyView.
Schematic of a metal‐oxide‐semiconductor field‐effect transistor at pinch‐off together with the channel potential. We revisit the problem of the potential distribution in an inversion channel field effect transistor (metal–oxide‐semiconductor field‐effect transistor) within the gradual channel approximation.
