An LC (LC) serial resonant circuit of a high-frequency modulation integrated circuit (IC)

摘要

The present invention relates to an LC (LC) series resonant circuit of a high-frequency modulation integrated circuit (IC). In particular, by replacing a SAW resonator having a weak point with respect to shock or static electricity and a multi-(LC) series resonant circuit of a high-frequency modulation IC capable of greatly reducing the material cost of a product.;A resonance circuit for generating a resonance frequency to be provided to a high frequency (RF) oscillation section of a high frequency modulation IC is replaced with an LC series resonance circuit instead of using a conventional SAW resonator, So that the reliability of the quality can be improved and the cost of the product can be reduced as compared with that by the SAW resonator.
