Abstract :
A multi-functional cardiac signal processor (CSP) with integrated sensor interfaces is designed for mobile healthcare applications, especially for heart activity diagnosis in different phases. Applying dedicated processing engines, the CSP extracts critical cardiac signal features based on compressed data with 90% storage reduction, while keeping the data network secure. Implemented in 90nm CMOS, the CSP consumes 22.6μW to 46.5μW at 0.5/1.0V in different configurations. Besides, the 10.2μW biopotential and 11.4μW capacitive sensor interfaces further enhance the system functionality.
