Abstract :
A low-voltage mixed-mode CMOS/SOI integrated circuit for 13.56 MHz RFID applications is presented. When connected to an external inductive loop antenna and put in a reader magnetic field, the chip is remote powered. Nominal supply voltage lowering down to 1.2 V (digital part) and 1.5 V (analog part) was achieved using a 0.25 μm partially-depleted CMOS/SOI technology. Device level simulations were done with the LETISOI model. Measurements proved the chip functionality and the suitability of the technology for lower voltages. To our knowledge, it is the first mixed-mode CMOS/SOI chip dedicated to RFID.
