Abstract
According to a first aspect of the present invention there is provided a signal generation system for generating a predetermined analog signal. The system comprises a clock generator () adapted for generating on the basis of an external clock signal a predetermined clock signal, a signal generator including a first gain stage () and a second gain stage () adapted for providing an overall gain of the signal generator and outputting a stepped analog signal, an analog filter () adapted for filtering the stepped analog signal output by the second gain stage and for outputting the predetermined analog signal, and a first and a second clock mapping units () adapted for receiving the predetermined clock signal, and respectively supplying to the first and second gain stages non-overlapped clock signal, wherein the amount of gain provided by the first and second gain stages is controlled by the non-overlapped clock signals. The present invention further relates to a signal generation method of generating discrete-time periodic analog signals suitable for a built-in self-test, as well as to a test method and system using the same.
