Power consumption is a key factor in analogue and digital design for portable devices. Radio Frequency IDentification (RFID) is widely used in industry, military and medical purposes. This technology operates with very low power consumption. Power consumption in passive tags is negligible and in fact, power consumption delimits the sensor tag's life-time and range. Many methods are proposed to reduce the RFID's power consumption, but new researches are demanded due to technological advancements and application growth. In this paper, a new scheme for time-to-digital converter was proposed which consumes a significant amount of energy in sensor tags.
