In fact, RTDs have been shown experimentally to have detection capabilities up to 2.5 THz and have been implemented as oscillators up to 712 GHz. However, RTD-based power sources have only demonstrated microwatt levels (i.e. <50 /spl mu/W) of performance above 100 GHz. Traditional RTD-based sources generate power by establishing limit-cycles which exchange energy with storage elements in the external circuit. Hence, in this implementation the amount of achievable output power will always be limited by external losses (e.g. contact resistance) and low-frequency design constraints (i.e. suppression of bias circuit oscillations). Recently, we have performed a comprehensive study of various nonlinear second-order circuit forms in an effort to reproduce the high-frequency self-oscillations observed in previous quantum-transport simulations of an RTD structure. A comparison between these two theoretical results allows one to deduce intrinsic oscillations which are free of external resonances.","PeriodicalId":326645,"journal":{"name":"1995 53rd Annual Device Research Conference Digest","volume":"77 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1995-06-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114151831","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

A predictive model is introduced which allows calculation of AM noise sideband power alongside carrier signals in HBT amplifers as a result of the upconversion of low frequency noise. These sidebands are an unavoidable result of the nonlinear components in microwave oscillators and power amplifiers which causes upconversion of intrinsic low frequency 1/f noise into amplitude modulated (AM) and phase modulated (PM) sidebands about the carrier. AM and PM sidebands degrade the spectral purity of the carrier which ultimately limits system performance in communication systems. Many works have described the upconversion process in microwave oscillators with its dominant phase noise, but less attention has been paid to the AM noise of power amplifiers. This work presents the theory of such noise in AlGaAs-GaAs HBT amplification and details a predictive model that allows calculation of AM noise sidebands for any HBT device.","PeriodicalId":326645,"journal":{"name":"1995 53rd Annual Device Research Conference Digest","volume":"102 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1995-06-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125412932","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The enhancement-mode MOSFET, used extensively in analog and digital circuits, has a particular advantage for high temperature operation because of its insulated gate. Research in this area has produced SiC n-channel depletion-mode devices/circuits and n-channel enhancement-mode digital gates operating from 25 to 300/spl deg/C. In this report, we demonstrate the first p-channel enhancement-mode MOSFETs and integrated circuits with good characteristics from 25 to 500/spl deg/C. The first enhancement-mode NMOS operational amplifier has also been fabricated and tested. The limited transconductance of SiC MOSFETs makes it difficult to produce sizable voltage gains without active loads.
