Abstract
The present technology relates to an oscillation apparatus and an oscillation method allowing a variation in a frequency of a clock signal to fall within a predetermined range without using a reference clock signal. An oscillation apparatus includes an oscillation section oscillating a clock signal, an adjustment section changing a parameter of a constituent element constituting the oscillation section to thereby adjust a frequency of the clock signal, and a calibration control section controlling the adjustment section to perform frequency calibration of the oscillation section in a case in which a variation in a frequency of the clock signal oscillated by the oscillation section falls within a second range exceeding a first range permitted in an application of the clock signal.
