Abstract: A radio frequency (RF) integrated circuit is provided. The RF integrated circuit supports carrier aggregation and includes first receiving circuits and a first shared phase locked loop circuit that provides a first frequency signal of a first frequency to the first receiving circuits. One of the first receiving circuits includes an analog to digital converter (ADC) and a digital conversion circuit. The ADC converts an RF signal received by the one of the first receiving circuits to a digital signal by using the first frequency signal. The digital conversion circuit generates a digital baseband signal by performing frequency down conversion on the digital signal.

Abstract: A comparator configured to calibrate an offset according to a control signal, including an input circuit configured to receive a first input signal and a second input signal, and to generate a first internal signal corresponding to the first input signal and a second internal signal corresponding to the second input signal; a differential amplification circuit configured to consume a supply current flowing from a positive voltage node having a positive supply voltage to a negative voltage node having a negative supply voltage, and to generate an output signal by amplifying a difference between the first internal signal and the second internal signal; and a current valve configured to adjust at least a portion of the supply current based on the control signal.

Abstract: Provided are a radio-frequency integrated chip (RFIC) and a wireless communication device including the RFIC. An RFIC configured to receive a carrier aggregated receive signal having at least first and second carrier signals may include first and second carrier receivers configured to generate, from the receive signal, first and second digital carrier signals, respectively. A phase-locked loop (PLL) may output a first frequency signal having a first frequency to the first carrier receiver and the second carrier receiver. The first and second carrier receivers may include first and second analog mixers, respectively, for translating frequencies of the receive signal, using the first frequency signal and the second frequency signal, respectively. Each of the first and second carrier receivers may further include a digital mixer for further translating the frequencies of the receive signal in the digital domain.
