A low leakage voltage pulse generator as needed in in I V small non-volatile memories for RFID applications is presented. vin in out o The voltage regulation loop is based on a capacitive divider which Charge pump v di, ad saves the static current usually consumed in a conventional pulse enable + e co generator based on a resistor divider. The proposed generator has been used in a 64bytes flash _ memory embedded in a RFID IC fabricated in a 0.22,u CMOS si lo 0d load process. Experimental results confirming the effectivness of the proposed generator are reported.
