摘要： An integrated circuit having integrated inductors includes at least one pair of transistors, and at least one inductor group which includes a pair of inductors coupled to the at least one pair of the transistor, respectively. The pair of the inductors form a spiral shape on a plane and the inductors arranged symmetrically to each other. Magnetic fluxes, which are generated by current flows along the inductors of the at least one inductor group, are formed in a direction to mutually intensify the magnetic fluxes according to differential signals applied to the at least one transistors from outside. Accordingly, high inductance and high quality factor can be attained owing to the positive magnetic coupling of the inductors.

摘要： In a chaotic signal generator, a first signal generator generates a first signal. The first signal includes a first fundamental wave having a preset first frequency and a plurality of harmonic waves of the first fundamental wave. A second signal generator generates a second signal. The second signal includes a second fundamental wave having a preset second frequency and a plurality of harmonic waves of the second fundamental wave. Also, a mixer mixes the first signal from the first signal generator with the second signal from the second signal generator to generate a chaotic signal having a sum frequency of the first and second signals and the harmonic waves of the first and second signals. A filter passes a signal of a preset band out of the chaotic signal from the mixer.
