Traditionally, a PLL is made as an analog building block. However, integrating an analog PLL in a digital noisy systems-on-a-chip (SoC) environment is challenging. In addition, the analog PLL is sensitive to process parameters. It is too hard to use the same analog PLL design in different process. On the other hand, the ADPLL has no off-chip components. It is made from standard cells found in most digital standard cell libraries. Therefore, the ADPLL has the higher immunity for power supply noise, temperature, and process variation.
In this thesis, the ADPLL consists of a digital phase frequency detector, a digital loop filter, a digital controlled oscillator and frequency divider. This thesis proposed a new architecture of digital controlled oscillator has good performance in terms of fine resolution. The ADPLL are developed by Verilog, and they are simulated by ModelSim 6.0i to justify the feasibility of the proposed ADPLL .
