A compact transmit/receive switch for 2.4 GHz reader-less active RFID tag transceiver
Radio frequency identification (RFID) is a ubiquitous identification technology nowadays. An on-chip high-performance transmit/receive (T/R) switch is designed and simulated in 0.13-μm CMOS technology for reader-less RFID tag. The switch utilizes only the transistor width and length (W/L) optimization, proper gate bias resistor and resistive body floating technique and therefore, exhibits 1 dB insertion loss, 31.5 dB isolation and 29.2 dBm 1-dB compression point (P1dB). Moreover, the switch dissipates only 786.7 nW power for 1.8/0 V control voltages and is capable of switching in 794 fs. Above all, as there is no inductor or capacitor used in the circuit, the size of the switch is 0.00208 mm2 only. This switch will be appropriate for reader-less RFID tag transceiver front-end as well as other wireless transceivers operated at 2.4 GHz band.
