    摘要: In a digital receiver, a noise attenuation and signal magnitude mapping variable amplifying unit includes a filter and an amplifier, amplifies and band-bass filters an analog signal and attenuating white noise and an interference signal other than a band signal. An ADC performs sub sampling on a carrier frequency of a desired signal and performs oversampling on the band of the desired signal by using a sampling frequency to convert the analog signal which has passed through the noise attenuation and signal magnitude mapping variable amplifying unit into a digital signal of a direct conversion frequency band or an intermediate frequency band. The ADC has a dynamic range for processing both the desired signal and an undesired signal adjacent to the desired signal. A digital signal processing unit converts a signal frequency of the digital signal or digital-filters an undesired signal within the digital signal and processes the digital signal by digitally adjusting a gain.

    摘要: Provided is a Q-boosting circuit for improving a Q factor in a radio frequency (RF) integrated circuit of a semiconductor device using a transformer instead of an inductor. The Q-boosting circuit couples a negative resistance circuit to a pair of terminals of a transformer to reduce a resistance component of the transformer, thereby increasing a mutual inductance component. Therefore, it is possible to obtain a more improved Q factor than a conventional Q factor through adjustment of an inductance and a resistance component, and to obtain the Q factor having a wide range from several tens to several hundreds according to a frequency range.
