Silicon Germanium Heterostructure field effect transistors have been proposed as a promising extension to the CMOS technologies affording enhanced performance at relaxed geometries. Particularly promising is the potential of SiGe Heterostructure MOS and Heterostructure FET at the law power operating regime. We discuss circuit design techniques applicable in the micropower regime which can be applied to SiGe HMOS technologies. We then review recent results in HMOS both from the material and the applications point of view. We conclude by reporting simulation results indicating the potential of SiGe HMOS in radiofrequency micropower applications.

Halkias G, Papavassiliou C, Perantinos G, Stathaki E, Turner J, Christou Aet al., 1992, Transimpedance amplifier design and performance for high BIT rate optical fiber local loop networks, Pages: 41-44

A Transimpedance Amplifier has been designed and fabricated using an established GaAs MMIC technology based on ion implanted GaAs MESFETs with 0.5 μm gate length, interdigital and overlay SiN capacitors, via holes and MESA resistors. The amplifier exhibits a transimpedance gain of 71 dBn over the-3 dB bandwidth of DC-2 GHz, a very low equivalent input noise current density of less than 2pA/√Hz and a DC power consumption of 0.62 W. After a series of design iterations, the state of the art amplifier was uniquely unconditionally stable with a large tolerance to external bias conditions.
