In passive UHF RFID transponders, a storage capacitor is used to supply the tag's subsystems. A quick charge of the storage capacitor and a sufficient supply voltage for the subsystems are intended for proper operation, thus using a voltage sensor. This paper presents two adjustable very low power consumption voltage sensor circuits for the supply capacitor(More)
The design of a fully integrated 2.4-GHz ISM-band transmitter for a localization application is presented. The signal path includes DAC, anti-alias filter, IQ-modulator and power amplifier. The clock generation part comprises voltage controlled oscillator, phase-locked loop and a quadrature clock generator. A novel quadrature clock generation scheme is(More)
