Abstract :
This paper presents a simple and accurate dynamic voltage divider for resistive bridge transducers which can be completely integrated in a standard CMOS process. Calibration is not necessary. The division ratio does not depend on the switch resistance of the applied switches. The charge injection and the voltage dependency of the resistors do not have any influence on the performance. Furthermore, the number of components is drastically reduced, compared to traditional dividers. Measurements on an integrated divider in a CMOS process show an accuracy of 13 bits
