The Impact of Ge Grading on the Bias and Temperature Characteristics of SiGe HBT Precision Voltage References
We analyze the effects that the Ge profile shape has upon the bias and temperature characteristics of SiGe HBT's. The widely used bandgap reference (BGR) design equation and a more general analytical expression we developed incorporating Ge grading are used to compare silicon devices to their SiGe counterparts. Measurement and simulation show that although the Ge-ramp effect is negligible in th...
متن کاملExtreme low temperature tolerance in woody plants
Woody plants in boreal to arctic environments and high mountains survive prolonged exposure to temperatures below -40°C and minimum temperatures below -60°C, and laboratory tests show that many of these species can also survive immersion in liquid nitrogen at -196°C. Studies of biochemical changes that occur during acclimation, including recent proteomic and metabolomic studies, have identified...
متن کاملOptimization of Early Voltage for Cooled SiGe HBT Precision Current Sources
The influence of Ge profile shape on the temperature characteristics of two key analog transistor parameters, Early voltage (VA) and current gain-Early voltage product (PVA), in SiGe HBTs have been studied over the temperature range of 300K-77K using SCORPIO, a transistor simulation tool calibrated to measured data [I]. A new version of SPICE that accounts for the temperature dependence of V, w...
متن کاملUniversity of Alberta VOLTAGE REFERENCES USING MUTUAL COMPENSATION OF MOBILITY AND THRESHOLD VOLTAGE TEMPERATURE EFFECTS
A voltage reference is an essential building block of many analog and digital circuits. The performance of a reference is gauged by the maximum variation in its allowable operating conditions. One of the most important specifications of a reference is its temperature drift. Therefore, special attention should be paid by the designer to the thermal behavior of a voltage reference. In this thesis...
متن کاملSection 7.1: Voltage References
Reference circuits and linear regulators actually have much in common. In fact, the latter could be functionally described as a reference circuit, but with greater current (or power) output. Accordingly, almost all of the specifications of the two circuit types have great commonality (even though the performance of references is usually tighter with regard to drift, accuracy, etc.). This sectio...
