Abstract :
In this paper, a frequency synthesizer architecture is proposed, employing a new analog-digital mixer based on signal coincidence, which achieves fast-settling, and high resolution compared with the conventional synthesizer. This new coincidence mixer, using digital error correction techniques, requires no output filters where sum and difference of input signal frequencies are obtained directly by separated outputs. The examples, related to new synthesizer are also presented. The new coincidence mixer is also realized and the measuring results are also given.
