Design of low power lfp amplifier and adaptive neural spike detection circuits

Abstract

The scope of this thesis work is motivated by implementation challenges of designing low power analog circuits for front end amplifiers and area efficient spike detector for neural recording microsystems The key challenge in the design of neural amplifier is large input DC offsets associated with the electrodes Neural signals superimposed on these offsets saturates the amplifier 8482 s front end One of the solution is to improve input linear range in order to accommodate offset voltages of up to newline newline
