A highly flexible numerical simulation model for the performance
prediction of brushless dc drives is presented, which is capable of
investigating unbalanced and asymmetrical operating conditions as well
as drives with non-ideal parameters. Numerical speed-up procedures
allow for the investigation of pulse-width modulated (PWM) drives using
a personal computer. Experimental...
The core area of a conventional CMOS digital gate
array consists of only one size of NMOS device and one
size of PMOS device. Both primitives have fixed minimum
channel lengths, and this has significantly impeded analog
applications. This work has shown that by forming series
and parallel interconnections between...
