This paper briefly reviews common state-of-the-art architectures of voltage regulators and their applicability to RFID. After that the design of a Low Drop-out (LDO) regulator using active resistances is presented, especially suitable for RFID applications. The chip is designed based on a 0.13 µm CMOS technology.
This paper presents a battery-less tire pressure monitoring system. Electro-magnetic field energy harvesting is utilized. The chip is also capable of RFID in a frequency range from 1MHz to 2.45GHz. The sensor data is transmitted either by an active transmitter at 868MHz or by employing the RFID feature. A bulk acoustic wave resonator is used as frequency(More)
Computer vision is becoming more and more important in the fields of consumer electronics, cyber-physical systems, and automotive technology. Recognizing and classifying one's environment reliably is imperative for safety-critical applications, as they are omnipresent, e.g., in the automotive or aviation domain. For this purpose, the Time-of-Flight imaging(More)
This paper at first illustrates implementation aspects and measurement results of a subcomponent for a multistandard RF identification (RFID) transponder. It is intended to be a common reference cell, both for basic UHF requirements and advanced application fields like local positioning and wireless sensing. Different single circuit topologies shown in(More)
