Abstract :
A CAD tool, MOSGRAD, that can be used to simulate the effects of distributed two-dimensional systematic and random variations in device parameters on the performance of matching-critical circuits has been developed. In addition to applications for layouts with conventional rectangular transistors, this tool can predict the performance of nonconventional circuit structures in which multiple drain and/or source regions share a common channel region as well as predict the performance of nonconventional layouts that may incorporate nonrectangular transistors or segmented transistors
