Titel
Integrated active sensors for near-field scanning
Abstract
This paper describes the design, simulation and measurement of integrated active sensors in OMMIC ED02AH GaAs technology for near-field scanning. Electromagnetic field simulation and on-wafer measurement have been performed for the miniature integrated sensors (loop and dipole). Two wideband amplifiers with a gain of 22 dB and 28 dB respectively and a bandwidth of about 10 GHz are designed and measurement results are presented. Finally, frequency responses of the active sensors are reported.
