A SiGe HMOSFET can be engineered to provide enhanced linearity in its output current-voltage characteristics. The additional linearity can he exploited in the design of more linear analogue circuits like the differential pair presented here. From the TCAD data of such a structure, the BSIM3v3 model of the transistor was extracted and simulation results were obtained for the performance of a differential pair. At the specified power of 1.25 mW the input range of the SiGe differential pair at which the percent nonlinearity is below 1%, is roughly twice that of its Si counterpart. Additionally the SiGe circuit is more power efficient since an increase of the power consumption from 1 mW to 1.25 mW accounts for an improvement of about 40% in its input range, as compared to only 10% for Si.
