PROBLEM TO BE SOLVED: To provide a receiver that can reduce a sneak path of noise from a crystal vibrator. SOLUTION: An analog circuit 20, an oscillator 30, a logic circuit 32, and a power supply circuit 34 which is components of the receiver are formed as a one-chip component 10. The power supply circuit 34 generates 2 kinds of operating voltages, applies a 1st operating voltage to the analog circuit 20, and applies a 2nd operating voltage which is lower than the 1st operating voltage to the oscillator 30 and to the logic circuit 32.
