Macromodeling and Optimization of Digital MOS VLSI Circuits

VLSI implementation of cross-coupled MOS resistor circuits

Abstract – This paper presents the cross-coupled MOS resistor circuits. The circuits consist of two internal pairs of NMOS and PMOS transistors, and their critical width and length parameters regulate the drain current, transconductance, and output drain resistance. Consequently it determines the output resistance of the circuits. The cross-coupled MOS resistor circuits can be used in multiplic...

The complexity of fault detection in MOS VLSI circuits

This paper considers the fault detection problem for a single fault in a single MOS channel-connected subcircuit. We identify the following three decision sub-problems : (i) decide if a test vector exists; (ii) decide if an initializing vector exists; and (iii) decide if a test pair is robust. We prove that each of these problems is NP complete. More importantly, we prove that the rst two remai...

Static Simulation of CNTFET-based Digital Circuits

   In this paper we implement a simple DC model for CNTFETs already proposed by us in order to carry out static analysis of basic digital circuits. To verify the validity of the obtained results, they are compared with those of Wong model, resulting in good agreement, but obtaining a lighter ensuring compile and shorter execution time, which are the main character...
