摘要：

In this paper we discuss the challenges in designing high-density biomedical neural implants. We discuss in more detail the constraints of the sense amplifier and the wireless link. Different techniques to design the front-end low-noise sense amplifier are discussed. We compare between different wireless designs and we show that trading off the transmitter power consumption and complexity with that of the external receiver will be mandatory to minimize the power dissipation and area of the implant.
