Abstract :
An analog adaptive filter for response correction of a load cell sensor is presented. The filter employs only transistors and therefore it can be integrated using digital CMOS technology, which is suitable for system-on-chip applications. To achieve adaptive compensation over a wide range of measurand, a novel CMOS multiplier was developed. The analog adaptive filter has been simulated using 0.35 μm 3.3 V BSim3v3 CMOS foundry models and found to perform effective compensation.
