Logic gate
circuits form the building blocks of digital electronics. In particular, it has
enabled microprocessor speeds to reach such high speeds today. Compressing
identical logic gate circuits to a certain scale region in a chip manufacturing
process brings with it certain problems. Logic gate circuits placed at the
nanoscale are generally in TTL (Transistor-Transistor-Logic) structure. This
ensures that it can work in harmony with both speed and operating units.
Millions of these nanoscale elements come together to form an operating unit.
Tolerance errors or differences caused by such a large number may force the
system to work stably. In this study, Monte Carlo Analysis was used with Pspice
circuit drawing package program. A special and widely used logic gate circuit
is discussed. This gate circuit is compared with 0% - 5% and 10% tolerance
values. Monte Carlo analysis, which is one of the advanced analysis methods,
gave us the current, voltage, power and performance responses of both identical
TTL circuits at different tolerance scales. Thanks to this analysis, which
offers a statistical evaluation feature, the number of samples, sigma value,
median value, mean values, maximum and minimum values can be interpreted in
detail. As a result, by using Monte Carlo Analysis method of a special TTL
circuit, it has been observed that the performance of the application circuits
increases as the tolerance values decrease.
