A Design of Analog Voltage-Mode Multiplier for UHF RFID in 0.18um CMOS process

35323

In this paper a “Low Voltage, Low Power, High Speed and High Linearity-CMOS Analog Multiplier for Modem ASK is proposed”. The multiplier circuit is implemented in 180nm CMOS technology. It can be operated even at low Supply voltage VDD=0.9V. Band width of operation is about 4.10MHz, which is suitable for high frequency/high speed applications. This device modulates an analog carrier signal to encode digital information, and also demodulates such a carrier signal to decode the transmitted information. The goal is to produce a signal that can be transmitted easily and decoded to reproduce the original digital data.
