Design Optimization of Transistors Used for Neural Recording

Figure 11

Use of the transconductance figure of merit to evaluate process changes. Effect of increasing oxide dielectric constant, increasing length or decreasing oxide thickness. The red line is a thick-oxide transistor; the black lines are from a thin oxide transistor. Both sets of curves are from transistors of a width of 100 μm and lengths L = 5 μm, 1 μm, and 0.5 μm from left to right.
