Abstract
A semiconductor device which is capable of shutting off the influence of noise introduced into a reference voltage while preventing an increase in die size. The semiconductor device including a reference potential generator, first and second filter, and first and second input circuit. The reference potential generator generates a reference potential in accordance with a first power supply. The first filter is connected to the first power supply and filters the reference potential to generate a first filtered reference potential. The second filter is connected to a second power supply and filters the reference potential to generate a second filtered reference potential. The first input circuit is connected to the first power supply and receives the first filtered reference potential to generate a first predetermined voltage. The second input circuit is connected to the second power supply and receives the second filtered reference potential to generate a second predetermined voltage.
