The Analog Mixed Signal Company Voltage Regulator Name Description ID: 042 VREG-10 VREG-10 This circuit was designed for a RFID chip in C7B12 C7B12. The purpose of this circuit is to imitate the V-I-characteristic of a Zener-diode to protect the chip from overvoltages. In this circuit, stacked NMOS transistors are used to adjust the threshold where the circuit starts to draw current. Low voltage transistors were used to get a smaller an faster circuit. 5 It was not designed for a long life time (10 hours).
