A 2.1µW real-time reconfigurable wearable BAN controller with dual linked list structure

A real-time reconfigurable network controller is proposed for wearable healthcare applications. Based on the dual linked-list structure, it can add or remove the nodes in the network during operation within 8µs and 500ms, respectively. To achieve low power consumption, three schemes of clock gating, low duty-cycled operation, and fixed-order allocation are proposed. As a result, the proposed network controller consumes only 2.1µW in average with 20MHz clock.
