Feasibility of picosecond electrical sampling using GaAs FET


A fully MESFET hybrid sampling system has been built and tested. The circuit includes an FET sampling gate, an FET sampling pulse generator, and an FET test step generator. These functions have been studied separately using a large-signal model and picosecond instrumentation. The parameters of each of them are optimized to obtain the best performances… (More)
