Abstract: A built-in jitter measurement circuit for a VCO (voltage-controlled oscillator) and a PLL (phase-locked loop) is disclosed. The circuit includes a divider for dividing frequency of a signal, a time to digital converter (TDC) for converting the period of the divided signal into digital values, a variance calculator for calculating variance of the period of the divided signal, a mean calculator for calculating mean value of the period of the divided signal, a encoder and counter for encoding and calculating the period of the divided signal, and a state controller as a controller for all other components. The circuit disclosed utilizes output clock of an opened-loop circuit to be measured and a divider for increasing jitter of the original signal. By measuring the bandwidth of a closed-loop circuit, accordingly, jitter of output clock of an opened-loop or an closed-loop circuit is measured by correlating the measured bandwidth and the jitter values from extrapolation.

Abstract: A computerized method for coloring a porcelain tooth includes a color difference comparison step, a first computer aided process, and a second computer aided process, for precisely controlling the color of the porcelain tooth. Each parameter is obtained from data comparison. The first computer aided process forms a first layer on the surface of the porcelain tooth and then and the second computer aided process forms a second layer on the first layer by way of computer aided manufacturing (CAM) according to the color difference comparison step. Because of CAM, the method does not require an experienced operator. Therefore, it may reduce labor cost, human error, and ceramic powder consumption. The method may thus save cost, improve production efficiency, and shorten delivery time of the porcelain tooth product.
