For the first time it was possible to obtain a current gain increase to more than 0 dB at frequencies beyond the transit frequency fT by use of an SiGe resonance phase transistor (RPT). This was achieved by using a very thick base layer with a graded

In the heterogeneous world of communication and radar systems, a steadily increasing number of technical approaches for different applications are observed. A new application on the horizon is the transmission of very high data rate streams (> 500 Mb

In heterojunction bipolar transistors current gain cut-off frequencies f 1 are limited by time constants of electron transport across the base and the collector space charge zone, This point of view favours the use of small widths of the base. Howeve

In this paper, the design of an active millimeter-wave frequency doubler using an Si/SiGe heterojunction bipolar transistor (HBT) as the active device is studied. Simulations are made using a developed physics-based large-signal model for Si/SiGe HBT

Silicon-based millimeter-wave integrated circuits (SIMMWIC's) can provide new solutions for near range sensor and communication applications in the frequency range above 50 GHz. This paper presents a survey on the state-of-the-art performance of this
