|
A 128-channel neural signal processor for implantable neural recording microsystems is presented. The
processor compresses the neural information of 128 simultaneous recording channels using discrete cosine
transform, achieving a compression factor of 69 at the expense of a 5.6proposed processor is implemented on register transfer level and synthesized in a 65-nm complementary
metal-oxide semiconductor process. The post-layout simulated power consumption at 1.2V is 33.06 μW
(258nW per channel) at an area cost of 0.46mm2.
