[en] Change in patients requirements has lead to new cochlear implants architecture specifications. In this paper, we proposed the receiver chain architecture study and design for new type of cochlear implants. Two receiver architectures were compared in terms of power consumption and Noise Figure, both of fundamental importance in biomedical embedded systems. SPICE simulations of the these architectures were carried out and transient results were presented for the solution retained. Furthermore optimization of the Low Noise Amplifier (LNA) using mathematical computations is presented, increasing the entire receiver performances.
