Abstract :
A new type of direct frequency synthesizer which can complete frequency switching in less than a microsecond is proposed. This yields low-spurious outputs by low-power analog integration circuit whose operating principle is similar to a digital accumulator. Experimental results confirm successful frequency synthesizer operation.
