CPC classification number: H04B1/0475 , H04B1/0483 , H04L27/04
Abstract: A transmitter includes a first channel and a second channel. The first channel includes a first mixer, and is used for processing a first input signal to generate a first output signal; the second channel includes a second mixer, where the second channel does not receive any input signal. When the transmitter is operated under a first mode, both the first mixer and the second mixer receive oscillation signals.

Abstract: Aspects of the disclosure provide methods and apparatuses for generating an internal reset signal that is synchronous to a clock signal. In some embodiments, an apparatus includes a clock switch circuit and a plurality of serially coupled D flip-flops (DFFs). The clock switch circuit receiving the clock signal can output the clock signal in an on state and block the clock signal in an off state. The plurality of serially coupled DFFs are coupled to the clock switch circuit and driven by the clock signal. If an external reset signal is enabled, the plurality of serially coupled DFFs can enable the internal reset signal. If the external reset signal is disabled, after a predefined number of clock signal cycles, the plurality of serially coupled DFFs can disable the internal reset signal.
