Abstract :
This paper presents the system level model of a transcutaneous optical telemetric link (TOTL) system for neural recording. Varieties of noise sources are characterized. Power distribution is described by means of Gaussian model approximation. Strategies for designing of the optical receiver that maximize signal to noise ratio (SNR) are discussed. The system level model presented here allows designers to compromise the TOTL receiver design for certain constraints: data rate, power consumption, thickness of tissue and receiver size.
