Abstract
This paper presents an on-chip characterization
method for random variation in minimum sized devices in
nanometer technologies, using a sense amplifier-based test circuit.
Instead of analog current measurements required in conventional
techniques, the presented circuit operates using digital voltage
measurements. Simulations of the test structure using predictive
70 nm and hardware based 0.13
m CMOS technologies show
good accuracy (error
5%–10%) in the prediction of random
variation even in the
