  • Publication number: 20170031441
    Abstract: A minimally invasive, wireless ECoG microsystem is provided for chronic and stable neural recording. Wireless powering and readout are combined with a dual rectification power management circuitry to simultaneously power to and transmit a continuous stream of data from an implant with a micro ECoG array and an external reader. Area and power reduction techniques in the baseband and wireless subsystem result in over 10×IC area reduction with a simultaneous 3× improvement in power efficiency, enabling a minimally invasive platform for 64-channel recording. The low power consumption of the IC, together with the antenna integration strategy, enables remote powering at 3× below established safety limits, while the small size and flexibility of the implant minimizes the foreign body response.

  • Patent number: 5502645
    Abstract: High level synthesis of datapaths has traditionally concentrated on synthesizing a specific implementation for a given computational problem. Methods to compose a reconfigurable BISR (built-in-self-repair) implementation with a minimum amount of area overhead are disclosed. Previously the BISR scope has been restricted to the substitution of operation modules with only those of the same type. Novel resource allocation, assignment and scheduling and transformation methods, primarily for ASIC designs, are described. These methods are based on the exploration of the design solution space accomplished by use of high level synthesis processes to find designs where resources of several different types can be backed up with the same unit.
