A balanced design of a universal sensor interface chip

In this paper a balanced design approach for implementing a universal sensor interface has been proposed. With such an approach, the consideration between the measurement accuracy and the flexibility/generality of the system has been balanced so that the resulting system can have a much wider application range and therefore more usefulness compared with the other similar solutions existing today. The system architect is explained in detail and some important implementation circuit blocks are also given. Such a circuit would lower the barrier of using sensors in electronics system so that more innovative systems can be invented.
