摘要
A reference voltage generation circuit includes a plurality of resistors that divide a prescribed input reference voltage into a plurality of divisional voltages and a plurality of analogue switches one of which selects one of the divisional voltages to output the selected divisional voltage as a desired reference voltage. Each of the analogue switches is formed of a transistor, and a size of the transistor is varied corresponding to a level of the reference voltage to be output.
