Design of 64-channel analogue multiplexer for neural application in CMOS 180 nm technology

This paper presents the design and simulation of the 64 channel analogue multiplexer for neural signal recording system designed in CMOS 180 nm technology. Single channel sampling rate is 100 kHz and linear range of the input signal is +/−400 mV. For noise cancellation caused by digital part of the differential architecture with dummy channel has been used.
