    摘要: Disclosed is a digital phase-locked-loop including: a time-to-digital converter (TDC) configured to output a digital bit based on an input clock and a reference clock, in which the TDC includes: a first arbiter group configured to compensate for a phase difference between the input clock and the reference clock with a first average offset and output a first logic value; a second arbiter group configured to compensate for a phase difference between the input clock and the reference clock with a second average offset and output a second logic value; and a signal processor configured to output the digital bit based on the first and second logic values.

    摘要: The inventive concept relates to a wireless communication receiver. The wireless communication receiver includes a second off-chip RF filter, an RF-to-digital converter and a digital pre-processor processing a signal converted into a digital. The RF-to-digital converter converts an RF signal being received into a digital signal of DC frequency band or intermediate frequency band and has a dynamic range that can process a wanted RF band signal and unwanted signals near to the wanted RF band signal. The digital pre-processor digitally controls a signal gain to transmit it to a modulator/demodulator.
