  • Patent number: 10951445
    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.

  • Patent number: 10693472
    Abstract: A clock generation apparatus includes a pulse generator configured to generate a pulse signal and a selection signal using a reference clock signal, a delay line circuit, a switch and a controller. The delay line circuit selects, as an input signal to a delay path, the pulse signal or a fed back portion of a delay clock signal at an output of the delay path, where the selection is based on the selection signal; and thereby generates the delay clock signal. The switch switches a first voltage or a second voltage to the delay line circuit for its operation, where the first voltage further provides power to the pulse generator. The second voltage is generated based on a phase difference between the reference clock signal and the delay clock signal. The controller generates a switch control signal based on a frequency of the delay clock signal.
