Pattern matching (PM) was first introduced as the semiconductor industry began to shift from simple one-dimensional rule checks to the two-dimensional checks required by sub-resolution lithography.

Analog circuits often use structures like differential pairs and current mirrors, where the matching of device characteristics such as the threshold voltage V t is important. Circuits using these ...

Analog designers have always had to worry about physical layout to get good matching of devices. Variations in doping levels across the chip, usually assumed to be in a gradient in one or two ...

Facility layout and design is an important component of a business’s overall operations, both in terms of maximizing the effectiveness of the production process and meeting the needs of employees. The ...
