Abstract :
This paper presents an ultra low power system architecture for self-powered sub-mW wireless biomedical sensor devices. The proposed architecture optimizes the power consumption by employing event-based mechanism to minimize the circuit activities, adopting reconfigurable circuits to increase the system flexibility, and using asymmetric asynchronous pulse-based transceiver to reduce the power of wireless communication.
