ABSTRACT:
There is provided a semiconductor device which can maintain a high tuning accuracy while suppressing a cost increase and suppress an increase in the time required for tuning. There are included, in addition to variable resistors configuring a level shift circuit, an additional resistor coupled between the output node of a VBGR voltage of a BGR circuit and one of the variable resistors and an additional resistor coupled between the other of the variable resistors and a reference voltage. N-channel MOS transistors are coupled in parallel with the additional resistors, respectively.
