Trade-offs in the design of a universal sensor interface chip

In this paper different design optimizations for implementing a universal sensor interface has been proposed. With those optimizations, the trade off between the measurement accuracy and the flexibility/generality in such a system has been optimized so that the resulting system can have a much wider application range and therefore more usefulness compared with other currently existing solutions targeting similar problems. The system architect is explained in detail and some important implementation circuit blocks are also given. Such a system would more efficiently help ease the process of interfacing sensors and eventually promote the design of smart systems in general.
