Abstract:
The present disclosure relates to the field of data converters. The data converters (Digital- to- Analog Converters and Analog- to- ADigital converters) typically consist of large capacitor and transistor arrays that are highly susceptible to systematic errors. The present disclosure discloses an array of systematic effect resilient matched devices for high resolution high speed data converters. Each of the devices is split into an integral number N of identical units connected in parallel. The identical units are spatially intermingled over an array having N rows and N columns, in a way that every column and every row of the array includes exactly one unit of all the devices and the sum of the systematic errors over the spatially distributed units is same for all devices, in order to compensate the systematic errors. A placement methodology along with one track routing solution for complete compensation of the systematic errors is also provided.

THE VISION
THE MISSION
ABOUT I-STEM
It has always been the basic tenet of the Government of India, in generously funding R&D efforts at academic institutions over the years, that facilities established through such support be made available to those needing them and qualified to make use of them for their own research work

However, this was never easy or straightforward for, among other reasons, there was no ready source of information of what facility was available and where. Thanks to the Web, it is much easier today to have a national and regional “inventory of resources”, so as to match users with the resources they need, and to do all this in an efficient and transparent manner.

This can lead to a leap in R&D productivity and greatly enhance the effectiveness of public investment. This is the motivation behind I-STEM.
