Semiconductor Device and RFID Tag Using the Semiconductor Device |
摘要 |
A semiconductor device monitors a voltage between a reference potential and an input potential and obtains a constant output potential regardless of a value of the voltage, after the voltage exceeds a predetermined threshold voltage in such a manner that the semiconductor device divides a voltage between the reference potential and the input potential using a plurality of first non-linear elements and at least one linear element to constantly generate a first bias voltage regardless of a value of the voltage, divides a voltage between the reference potential and the input potential using a plurality of second non-linear elements with reference to the first bias voltage to constantly generate a second bias voltage regardless of a value of the voltage, and determines the output potential with reference to the second bias voltage.
