Switched-Current Analog Adaptive Filter for Load Cell Response Correction

This paper introduces the switched-current technique to develop an analog adaptive lter for load cell sensor response correction. The lter employs only transistors and therefore it can be integrated using stan- dard digital CMOS technology, which is suitable for System-on-Chip applications. To perform adaptive com- pensation over a wide range of measurand, a novel CMOS multiplier circuit is developed. The analog adap- tive lter has been designed and simulated using 0:35 m 3.3V BSim3v3 CMOS foundry models and found to achieve e ective compensation.
