Abstract
In a circuit and a method of clock interpolation, an input signal at a first frequency is processed and at least one output signal having a second frequency being a multiple of the first frequency of the input signal is output. The circuit is defined by the fact that the input signal is measured with respect to frequency and phase in a PLL frequency measuring circuit, and by the fact that the measured input signal is multiplied by at least one frequency multiplier and an oscillator that follows the frequency multiplier.
