Resumen:	This paper presents two ultra-low-power voltage sensors and a voltage protection, to optimize the charge of the Supply Capacitor in passive UHF RFID sensors. The state-of-the-art in the field is analyzed and compared with the proposed circuits using a 0.35 μm 2P4M CMOS process. The measured current consumption of the Voltage Sensors are 70 nA and 0.2 nA at 3.3 V. The Voltage Protection circuit consumes less than 60 nA at 3 V. Additionally, a low power consumption voltage regulator is presented. Experimental results prove its proper operation.
