Abstract
A reference power generating circuit and an electronic circuit using the same are provided. The reference power generating circuit includes a first bandgap reference circuit and a second bandgap reference circuit. The first bandgap reference circuit is biased by a power voltage to generate a first reference voltage, where the first reference voltage has a first offset. The second bandgap reference circuit is connected to the first bandgap reference circuit in series and receives the first reference voltage generated by the first bandgap reference circuit. The second bandgap reference circuit is biased by the first reference voltage to generate a baseline reference voltage. The baseline reference voltage has a second offset, and the second offset is smaller than the first offset.
