Abstract: One of the frequently used IC in bio-medical instruments for multiplexing the various signals is Analog multiplexer. This paper demonstrates the design of low voltage, low power CMOS analog multiplexer, using pass transistor logic for bio-medical application. The design goal is to achieve minimum power dissipation and minimum ON resistance with wide range of low voltage and low frequency of operation. The above goals are met by selection of proper technology parameters and by enhancing the design using minimum number of NMOS Pass transistor. Modified pass transistor logic is proposed, which replaces the traditional pass transistor logic for designing a multiplexer and require less no. of transistors. The ON resistance of 10Ω is achieved and the power dissipation of around 10nW is achieved in this design. Design and analysis is performed using 45 nm CMOS technology in CADENCE IDE.
