Embedded Medical Microsystems

This chapter presents dedicated circuit techniques and strategies to design and assemble dense embedded microsystems intended for bioelectrical signals recording applications. Efficient interfacing circuits to measure the weak bioelectrical signal from several cells in the cortical tissues are covered, and high-fidelity data-reduction strategies are demonstrated. Also, on-chip power management schemes based on automatic biopotential detection are presented to decrease power consumption of neural recording implants by an order of magnitude. In addition, low-power design techniques, ultra-low-power neural signal processing circuits, and dedicated implementation strategies enabling for high-density multi-channel neural recording microsystem integration are also covered.
