摘要:
A perovskite-oxide lamination constituted by a substrate and one or tore first films of a first oxide of a perovskite type and one or more second films of a second oxide which are alternately formed over the substrate. The first oxide has a composition expressed as ABO3, the second oxide has a composition expressed as CDO3, each of A and C represents one or more A-site elements which are one or more metal elements, each of B and D represents one or more B-site elements which are one or more metal elements, O represents oxygen, and the second oxide is unable to be formed to have a perovskite crystal structure at normal pressure without a thickness limitation. The one or more first films and the one or more second films may contain inevitable impurities.

摘要:
An oscillator control apparatus has a digitally-controlled oscillator which outputs an oscillation signal having an oscillation frequency in response to an oscillator adjusting signal, a counter which counts the oscillation signal and outputs a count in response to a reference signal in synchronism with the oscillation signal, a time-to-digital converter which calculates a phase difference between the oscillation signal and the reference signal, an adder which adds the count and the phase difference and outputs the added value as first phase information, a corrector which corrects the first phase information in response to a phase control signal for setting an oscillation frequency of the digitally-controlled oscillator when a time difference between a rising-up timing of the oscillation signal and a rising-up timing of the reference signal is less than a predetermined time, and outputs second phase information, and a filter for smoothing a difference between the phase control signal and the second phase information, to output the oscillator adjusting signal.
