Re-interpreting the MOS transistor via the inversion coefficient and the continuum of g/sub ms//I/sub d/

A method of interpreting MOS transistor behavior is described which is simple yet fundamental and universal. Device currents are normalized to the inversion coefficient (IC) and interpreted via g/sub ms//I/sub d/. Measurements confirm this behavior, and demonstrate the need for the development of proper model forms for usage of this description. This interpretation also connects directly with modern analog CMOS design needs, allowing for the positive use of moderate and weak inversion, in a manner which permits a coherent evolution of a design toward the final goals.
