Abstract:
|
This paper describes a design methodology for the basic current
source cell circuit of high-speed high-accuracy current steering
DIA conveners taking into account mismatching in all the
transistors of the cell. Previous works consider arbitrary safety
margins in the sizing process. The presented approach allows a
more accurale selection of the optimal design point. The design
methodology is illustrated for a particular design of a 0.35pm
CMOS 12-bit 400 MHz current-steering segmented DIA converter. |
