Abstract

With the advent of modern CMOS technologies in recent years, the intrinsic variability of analog circuits has become a significant enough problem for circuit designers that special methods have become necessary to address this issue from a perspective of variability. In an extreme environment context, the situation becomes even worse, as the effect of temperature in particular can add further significant variation in performance. The final problem to be overcome is that in extreme environments, almost by definition it can be difficult or even impossible to access the equipment to perform recalibration, making techniques that can modify circuit performance in the field particularly valuable.
