The above- stated modeling limitations are a great nuisance when it comes to design, since the square- law hand calculations described in textbooks typically won’t match simulations for a classical flow (see Figure 1.2). Modern circuit simulation relies on complex device models such as BSIM6 [6] or PSP1 [7], which are carefully crafted to reflect the “real” device characteristic in Figure 1.1. The result is a significant disconnect between hand analysis and simulation results, and consequently,designers tend to shy away from hand- calculations and resort to a design style built on iterative and time- consuming SPICE- based “tweaking.”
