The design of a fully-integrated \Delta\Sigma-controlled fractional-N frequency synthesizer is described. Using a dual modulus 64/72 prescalar based on injection locking technique and a novel third order digital \Delta\Sigma modulator, we achieved an extremely low power synthesizer in 2.5GHz band.. Total power dissipation of the frequency synthesizer is less than 6mW at a 1.5V supply. The loop bandwidth is optimized to achieve a -123dBc/Hz phase noise at 3MHz offset frequency. The locking time of the loop is less than 30?s.
