Patent ID: 6850049

Claim:
A semiconductor device comprising a voltage conversion circuit for converting a voltage value of an input voltage according to temperature change and outputting an output voltage, wherein said voltage conversion circuit includes: an input section having a first transistor connected between a first voltage line and a first node, and carrying an input current by applying said input voltage to said first transistor; a current-mirror section having a second transistor connected between said first node and a second voltage line supplying a different voltage from a voltage supplied by said first voltage line, and a third transistor connected between a second node, to which an output current according to said input current is carried, and said second voltage line, and forming a current-mirror by said second and third transistors; an output section having a fourth transistor connected between said second node and said first voltage line, and outputting said output voltage according to said output current from said second node; and a resistance section connected only one of between said second voltage line and said second transistor and between said first voltage line and said fourth transistor, and provided only as a resistance element in said voltage conversion circuit.
