Dynamic Sensor Compensation Using Analogue Adaptive Filter Compatible with Digital Technology.
Accepted for publication in IEE Proc. Circuits, Devices & Systems
An analogue adaptive filter for dynamic response compensation of a load cell sensor is presented. The filter employs only transistors and therefore it can be integrated using standard digital CMOS technology, which is suitable for System-on-Chip applications. To perform adaptive compensation over a wide range of measurand, a novel CMOS multiplier circuit was developed. The analogue adaptive filter has been designed and simulated using 0.35um 3.3V BSim3v3 CMOS foundry models and found to achieve effective compensation.
