Title Proper : A CHOPPER MODULATED AMPLIFIER SYSTEM DESIGN FOR IN VITRO NEURAL RECORDING
Note : This document is digital این مدرک بصورت الکترونیکی می باشد
Abstract : Neural recording systems measure very low-amplitude signals of less than 5 kHzbandwidth. Low-frequency noise processes such as flicker noise and DC offset can degradethe quality of recordings made by such systems. A chopper modulated amplifier system isdescribed and shown to reduce the flicker noise in neural recording systems by 10 to 20 dB.The amplifier system was implemented using the MOSIS ABN 1.5 micron technology.While the amplifier system contained an imperfection that prevented it from working withactual tissue samples, it worked well enough to prove that chopper modulation does reduceflicker noise appreciably. All of the details are presented along with studies of gate-metalfreetransistors and custom-made MOSIS-based recording electrodes..
