| Abstract: | The principle of PLL voltage-frequency-narrow pulse con version circuit and its micro-consumption mechanism is described . On the basis of the characteristics of PLL and its dependance on the variation of environment temp erature, the method of optimizing linearity is introduced, and the compensation circuit for improving the frequency-temperature characteristics is specified. Su ch a circuit has been successfully applied in the head of the fiber optically po wered current transducer for HV line, and the energy consumption of this circuit is no more than 0.3mW. |
