Feasibility of a cryogenic SiGe amplifier at 4 K

    The feasibility of an integrated SiGe amplifier with 1 GHz band width and 30 dB gain for cryogenic temperatures has been studied. The standard models do not simulate special low temperature phenomena and give erroneous results below 50 K. We have circumvented this problem by using an experimentally defined “effective temperature” in simulations. Thereafter we have studied a cascade amplifier topology with trade-offs between gain, noise figure, band width, area and power consumption.
