—An ultra-low-power four-channel sensor interface for wireless sensor networks employing semi-active RFID transponders as sensor nodes is described in the present paper. Each channel is based on a self-contained switched-capacitor second-order single-bit Σ∆-modulator operated in an incremen-tal manner. The power consumption can be regulated through(More)
— The RF frontend is one of the key elements in passive transponders, accounting for such diverse operations as RF-DC conversion, voltage regulation, modulation and demodulation of the incident RF wave. In this paper, the design of a high-performance frontend for passive RFID transponders under the international standard ISO/IEC 18000-4/6 is presented. Its(More)
