Abstract :
In this work a new triode geometry has been designed to reduce the cathode-gate capacitance with respect to the classic Spindt Type microtriodes. With this configuration, the cut off frequency has been increased up to 156 GHz, about 3 times bigger when compared to the standard configuration.
