Comparison of Receiver Architecture in Terms of Power Consumption and Noise Figure for Cochlear Implants Application

Change in patients requirements has lead to new cochlear implants architecture specifications. In t his paper, we proposed the receiver chain architecture study and design for new type of cochlear implants. Two receiver archite ctures were compared in terms of power consumption and Noise Fi gure, both of fundamental importance in biomedical embedd ed systems. SPICE simulations of the these architectur es were carried out and transient results were presented fo r the solution retained. Furthermore optimization of the Low Noise Amplifier (LNA) using mathematical computations is presented, increasing the entire receiver performances.
