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 ...

A schematic diagram is not a detailed blueprint of an analog circuit; instead, it’s more like architectural sketch of the circuit. Look at any schematic for a CMOS analog IC circuit and you will see ...

With small geometry silicon processes, additional nonfunctional geometric structures are required to maintain layer planarity during the chemical/mechanical polishing (CMP) phase of processing. The ...
