ABSTRACT:
A reference voltage generation circuit includes a positive polarity ladder resistor circuit including a first ladder resistor circuit having resistance ratio for a positive polarity and a negative polarity ladder resistor circuit including a second ladder resistor circuit having resistance ratio for a negative polarity. First to2i-th reference voltage output switching circuits are respectively inserted between first to i-th and (i+1)th to2i-th division nodes and first to i-th reference voltage output nodes. The positive polarity ladder resistor circuit generates a reference voltage at a positive polarity inversion period and the negative polarity ladder resistor circuit generates a reference voltage at a negative polarity inversion period.
