Abstract--This paper presents work on ultra-low-power circuits
for brain­machine interfaces with applications for paralysis pros-
thetics, stroke, Parkinson's disease, epilepsy, prosthetics for the
blind, and experimental neuroscience systems. The circuits include
a micropower neural amplifier with adaptive power biasing for use
in multi-electrode arrays; an analog linear decoding and learning
architecture for data compression; low-power radio-frequency
(RF) impedance-modulation circuits for data telemetry that
minimize power consumption of implanted systems in the body;
a wireless link for efficient power transfer; mixed-signal system
integration for efficiency, robustness, and programmability; and
circuits for wireless stimulation of neurons with power-conserving
sleep modes and awake modes. Experimental results from chips
that have stimulated and recorded from neurons in the zebra
