1. 1. A 200 GHz Subharmonic Resistive Mixer and an IF Amplifier Based on GFETs

   University essay from Chalmers tekniska högskola/Institutionen för mikroteknologi och nanovetenskap

   Author : Yaxin Zhang; [2016]
   Keywords : Graphene; GFETs; subharmonic resistive mixers; small-signal amplifiers; CPW technology; integrated circuits ICs ;

   Abstract : In recent years, graphene, a two-dimensional monolayer of carbon atoms, has rapidly attracted great attention in high-speed electronics. The promising property such as the high intrinsic carrier mobility as well as high carrier saturation velocity make graphene a potential candidate for high-speed transistors operating in the millimeter wave and the terahertz frequency ranges.

3. 2. Noise Characterisation of Graphene FETs

   University essay from Chalmers tekniska högskola/Institutionen för mikroteknologi och nanovetenskap

   Author : Michael Andersson; [2012]
   Keywords : Graphene FETs; microwave amplifiers; noise measurements; noise figure; subharmonic resistive mixer;

   Abstract : This thesis deals with the first noise performance study of graphene field effect transistors (G-FETs) at microwave frequencies. It considers G-FETs in two different applications, as a subharmonic resistive mixer and in an amplifier. The work encompasses cleanroom fabrication, as well as characterisation by measurement and modelling. READ MORE
