Homodyne detection in graphene FET power detectors

Konferensbidrag (offentliggjort, men ej förlagsutgivet), 2018

We have analysed the specific nonlinearity of GFETs, and demonstrated that the input RF signal should be coupled to both drain and gate to obtain the highest dc current response of GFET power detectors. To enhance the response further, one can use an extrinsic capacitor between gate and drain, and optimise the GFET channel dimensions
