Regulator circuit and RFID tag including the same in wireless communication to improve noise margin |
摘要 |
One object of the present invention is to provide a regulator circuit with an improved noise margin. In a regulator circuit including a bias circuit generating a reference voltage on the basis of the potential difference between a first power supply terminal and a second power supply terminal, and a voltage regulator outputting a potential to an output terminal on the basis of a reference potential input from the bias circuit, a bypass capacitor is provided between a power supply terminal and a node to which a gate of a transistor included in the bias circuit is connected.
