A high-speed four-phase 25% duty cycle clock generator is provided. The four-phase clock generator includes a four-stage ring structure including four transistors of a first conductivity type, each transistor configured as a common-source structure and interconnected in a ring topology to sequentially and cyclically reset phases of an output clock; a first alternating phase cross-coupled pair including two transistors of the first conductivity type to cross-couple a first and third phase of the output clock; a second alternating phase cross-coupled pair including two transistors of the first conductivity type to cross-couple a second and fourth phase of the output clock; and a set network including four transistors of a second conductivity type to sequentially and cyclically set the phases of the output clock in response to four gated clock signals generated by alternately gating phases of an input clock and the phases of the output clock.

The present application relates to a kind of multi-mode noise interference signal generation method, belong to signal interference technical field, solve the problem that existing cannot dynamically flexibly generate the interference signal of multiple modulation modes and the high development complexity.For method includes: according to noise kind and interference mode, obtain first noise sequence, second noise sequence, third noise sequence, noise interference bandwidth and center frequency;Carrier signal is generated based on center frequency;First noise sequence and noise interference bandwidth are passed into first multiplier, then the output result and carrier signal are passed into adder, and first complex signal is output by direct digital synthesizer;First complex signal and second noise sequence are passed into complex multiplier, and second complex signal is output;Second complex signal and third noise sequence are passed into second multiplier, and noise interference signal is output.The generation of multi-mode noise interference signal dynamically flexibly is realized.
