Voltage divider circuit and semiconductor device
Provided are a voltage divider circuit with high detection precision, a small circuit area, and a reduced chip size, and a semiconductor device including the voltage divider circuit. The voltage divider circuit includes: a first resistor circuit formed to have a resistance that is weighted according to a binary code; a second resistor circuit formed to have a resistance that is weighted according to the same binary code; and a third resistor circuit including a third resistor having a resistance that is weighted according to the same binary code to have a maximum weighted bit count, in which both ends of the third resistor are alternatively connected to an output terminal by two transmission gates.
