Characterization and Digital Signal Integrity Analysis of PHEMTs using an Eye Diagram

Fardeen Dendru

Abstract


Digital Performance analysis of high electron devices used in microwave communication systems is crucial for ensuring their suitability to ever-increasing high-speed data rate applications. This study aims at characterizing a 0.5x200μm dimension pseudomorphic heterojunction transistor and studying the effect of the device characteristics on various parameters of digital bit streams. It has been found that while the device can be predicted to be suitable for a wide range analog bandwidth application however digital application can be satisfactory only in a narrower range only and that a correlation has been established between digital bit rate and various small signal parameters of the device.
