A new method of designing a very high bandwidth semi-digital PLL with a large operating frequency range from 100MHz to 1GHz is proposed. The PLL is modelled in Z-domain. The simulation results is also matched with the modelling to ensure that the PLL is stable for very high bandwidth. The bandwidth achieved is (1 over 4)th of the input reference frequency for the whole operating range mentioned.
