Design Analog Buffering on The multiplexer in RFID sensor tag with CMOS Technology 0.35 a#956;m

Abstract

Abstract-This paper describes the 'buffering system in the RFID sensor tags'. Buffer circuit function is used in the data selection as a buffer. Two-sensor output which is an analog signal by a multiplexer owns a possibility of a very low value. The buffer circuit is required to maintain the signal in order to prevent the dropped voltage. Its uses two inverters functioned as a noninverting amplifier. The conclusion is that the buffering circuit is able to keep the voltage level by amplification of 1.
