Abstract
Spatial gradients often limit the matching accuracy of element arrays in ADC's and DAC's. We cast. the problem of spatial gradients formally and present a global optimization-based solution that does not require the gradients to be pre-characterized precisely or limit them to being linear and/or quadratic. Si results from a standalone BiCMOS DAC and a CMOS DAC, part of the industry's first DOCSIS 1.1 certified cable modem solution, are presented.
