Patent ID: 11899487
Assignee: WILL SEMICONDUCTOR CO., LTD.SHANGHAI
Field: Control (Instruments)
Classification: CPC G | IPC G

Claim 4:
5. The reference voltage circuit according to claim 2, comprising:
a sixth transistor, through which a sixth current corresponding to the reference voltage is made to flow;
a fourth transistor, through which a fourth current is made to flow, the fourth current corresponding to the greater current of a current corresponding to a current flowing through the first transistor or the second transistor and the sixth current;
a fifth transistor, through which a correction current obtained by subtracting the sixth current from the fourth current is made to flow; and
a correction resistor, which is disposed between both the first current path and the second current path and ground, and through which the correction current is made to flow in addition to currents flowing through the first current path and the second current path; wherein
temperature dependence of the reference voltage is further corrected.
