Abstract

Bowel signal monitoring finds numerous applications in medical and pathological fields. A portable bowel sound monitoring system requires front end amplifiers, data converters, signal processors and power efficient operation. In this paper, a low power integrated bowel sound monitoring system has been proposed and implemented. The system consists of a tunable charge amplifier, a feature extraction block, a bowel sound detection unit and a bowel sound occurrence rate count block. The system is implemented in a standard 6 metal 1 poly 180nm CMOS process. The developed integrated system consumes 52μW of power from a 1V supply.
