Computer-aided analysis of MOSFET-inverter circuits using normalized variables

A general approach to analysis and design of MOSFET-inverter circuits is presented. This approach includes the use of normalized variables in conjunction with an accurate MOSFET model in which important effects, such as body effect and channel shortening, are taken into account. Design curves of normalized delay parameters and power-delay product can be used as a design tool and as a means of comparing different static MOSFET-inverter types. The normalization procedure is independent of MOSFET device scaling rules.
