Optimized LNA for analog RF front-end circuit in brain-machine interface

Abstract

Advances in hardware technology, and wireless network have led to widely usage of implantable wireless micro-systems. These applications demand for small, low-cost, and low-power wireless transceivers. One of the most important blocks in wireless receivers is the low-noise amplifier (LNA). This paper presents a biasing optimized LNA for analog front-end circuit in brain-machine interface. An optimized biasing technique is thoroughly analyzed first in this paper, and a LNA circuit is designed based on this technique.
