Abstract :
An implanted fully-integrated 65nm CMOS 1.1mm × 1.1mm × 0.8mm remotely-powered wireless transponder for implantable neural sensors provides 5uW for sensor interfaces, while consuming 3uW and transmitting 2Mbps at 330fJ/b without violating exposure limitations. This is accomplished by combining a time-multiplexed power and data transmission scheme with a reflective impulse transmitter architecture.
