Abstract

We propose an ASK modulator and Antenna driver for multi-standard 13.56 MHz RFID readers and NFC devices. The proposed transmitters of RFID readers and NFC devices consist of ASK modulator, inverting output driving buffer and off-chip antenna with a matching circuit. The ASK modulation depth can easily be controlled by adjusting duty ratio by the delay line circuit. The test chip was fabricated by using a 0.35 μm double poly CMOS process. The measured results demonstrated that the proposed circuit has met the standard specifications.
