Power consumption is a key issue in today's digital and analog design for various portable devices. Radio frequency identification (RFID) is a technology which requires very low power and it uses electromagnetic waves in the radio frequency to transmit the ID of objects. It has a broad range of uses although inventory management and tracking are the most common. A low power demodulator, part of a RFID transponder operating in the 900 MHz range, is presented using sub-threshold design. Using this technique and working with 90 nm complementary metal-oxide-semiconductor (CMOS) technology, the circuit can operate with a supply voltage as low as 0.3 V, consuming a very small amount of power compared to other demodulators in the literature, making it suitable for ultra-low power applications.
