Reference voltage generating circuit and receiver circuit |
摘要 |
Disclosed is a reference voltage generating circuit including a constant current circuit which comprises: a first resistive element and a bipolar transistor connected in series between a supply voltage terminal and a constant potential point; a first MOS transistor having a gate connected to a node connecting the first resistive element with the bipolar transistor; a second resistive element connected in series between a source of the first MOS transistor and the constant potential point; a second MOS transistor connected between a drain of the first MOS transistor and the supply voltage terminal; and a third MOS transistor forming a current mirror in conjunction with the second MOS transistor,
wherein a constant current generated by the constant current circuit or a current proportional to the generated constant current is converted to a voltage as a reference voltage. |
