Abstract
Methods of improving operational parameters between at least a pair of matched transistors, and a set of transistors, are disclosed. One embodiment of a method includes a method of improving at least one of a threshold voltage (Vt) mismatch and current drive between at least a pair of matched transistors for analog applications, the method comprising: forming at least a pair of transistors, each with a gate having a plurality of connected fingers; and optimizing a total length of a channel under the plurality of fingers to attain at least one of: a) a reduced threshold voltage mismatch between the at least pair of transistors, and b) increased current drive for a given threshold voltage mismatch, between the at least pair of transistors, each finger having a length less than an overall length of the channel.
