Abstract :
The main design trade-off in the realization of a low power PLL are presented and followed by the description of one implementation. This PLL is designed for mobile communication ASICs, it multiplies frequencies over 8 MHz by a factor of 2 to 8, with a maximum output frequency of 200 MHz. Its power dissipation is less than 600 μW at 200 MHz and 1.8 V. These performances are achieved mainly on the account of the VCO structure choice and the current source design
