Abstract
A signal generator having a switching function includes a first oscillation circuit, a second oscillation circuit, a frequency-division circuit and a combination circuit. The first oscillation circuit outputs a first frequency signal having a first frequency and a reset signal synchronized with the first frequency signal. The second oscillation circuit outputs a second frequency signal having a second frequency which is N times higher than the first frequency. The frequency-division circuit frequency-divides the second frequency signal by N, resets a value for frequency-division based on the reset signal and generates a divided second frequency signal. The combination circuit combines the first frequency signal and the divided second frequency signal and outputs a combined signal.
