Abstract
In accordance with various embodiments, a method for sampling an input signal may be provided, wherein the method may include providing a single frequency clock signal; selecting clock pulses from the single frequency clock signal in a random manner to generate a spread spectrum clock signal; and sampling the input signal using the spread spectrum clock signal. A corresponding device for sampling an input signal may be provided.
Claims15
A method for sampling an input signal, the method comprising:
- providing a single frequency clock signal;
- randomly selecting at least one clock pulse from the single frequency clock signal;
- delaying at least one of the randomly selected clock pulses by a random delay time to generate a spread spectrum clock signal;
- sampling the input signal using the spread spectrum clock signal.
