The self-injection-locked integrated circuit includes voltage-controlled oscillator, mixer, two amplifiers and harmonic-frequency power combiner. A frequency-multiplied signal is produced by amplifiers and harmonic-frequency power combiner then transmitted to a living body by transmitting antenna. A frequency-divided signal is produced by voltage-controlled oscillator and mixer then transmitted to voltage-controlled oscillator, then a frequency- and amplitude-modulated signal is produced by the voltage-controlled oscillator then transmitted to demodulator to produce a vital sign. So as to detect vital sign with a higher frequency to increase measurement sensitivity by using a low-cost integrated circuit process. A centrifugal compressor includes a volute base block, a volute cover plate, an impeller, a diffuser-adjusting assembly, a radial constraint assembly, an axial constraint assembly and a driving assembly.
