Battery-less passive sensor tags based on RFID or NFC technology have achieved much popularity in recent times. Passive tags are widely used for various applications like inventory control or in biotelemetry. In this paper, we present a new RFID/NFC frontend IC (integrated circuit) for 13.56 MHz passive tag applications. The design of the frontend IC is compatible with the standard ISO 15693/NFC 5. The paper discusses the analog design part in details with a brief overview of the digital interface and some of the critical measured parameters. A novel approach is adopted for the demodulator design, to demodulate the 10% ASK (amplitude shift keying) signal. The demodulator circuit consists of a comparator designed with a preset offset voltage. The comparator circuit design is discussed in detail. The power consumption of the bandgap reference circuit is used as the load for the envelope detection of the ASK modulated signal. The sub-threshold operation and low-supply-voltage are used extensively in the analog design—to keep the power consumption low. The IC was fabricated using 0.18 μm CMOS technology in a die area of 1.5 mm × 1.5 mm and an effective area of 0.7 normalmm2. The minimum supply voltage desired is 1.2 V, for which the total power consumption is 107 μW. The analog part of the design consumes only 36 μW, which is low in comparison to other contemporary passive tags ICs. Eventually, a passive tag is developed using the frontend IC, a microcontroller, a temperature and a pressure sensor. A smart NFC device is used to readout the sensor data from the tag employing an Android-based application software. The measurement results demonstrate the full passive operational capability. The IC is suitable for low-power and low-cost industrial or biomedical battery-less sensor applications. A figure-of-merit (FOM) is proposed in this paper which is taken as a reference for comparison with other related state-of-the-art researches.

“…The differential output is fed back to VREFP_ODD, VREFN_ODD, VREFP_EVEN and VREFN_EVEN through a tunable capacitor to obtain the hysteresis function. The hysteresis voltage is shown in equation (1). The offset tuning function is also added for compensation of the system offset and other applications usage.…”

“…Amplitude Shift Keying (ASK) modulation or demodulation scheme has been widely used in many communication systems, such as near field communication (NFC) [1] or radio frequency identification (RFID) tag [2]. As the mobile devices are the key market driver, higher demand on high data rate with low power design is needed.…”

In this paper, an Amplitude Shift Keying (ASK) demodulator circuit for Near Field Communication (NFC) target mode or Radio Frequency Identification (RFID) tag is designed by using sample and hold method. It features envelope detector, switch capacitor filter, dynamic comparator, clock extractor and phase generator. This demodulator was demonstrated and simulated in TSMC 0.18um CMOS technology with an average power of 32uW power consumption at 13.56Mbps Non-Return-to-Zero (NRZ) date rate for a carrier frequency of 13.56MHz. The minimum input voltage swing is 200mVpp.
