    Abstract

    An all digital phase locked loop was implemented, in 0.25 micron CMOS technology, by understanding the analog phase locked loop concepts and the digital conversion required to maintain the same functionality. The all digital phase locked loop achieves locking within about 100 reference clock cycles. The pure digital phase locked loop is attractive because it is less sensitive to noise and operating conditions than its analog counterpart.

    Many circuits currently face the problem of clock skew, and registers and flip-flops are not receiving the clock at the exact same time. The clocks are generated by oscillators, but the clocks that reach the registers and flip-flops are distorted and require a phase locked loop to address this problem. A phase locked loop ensures that the clock frequencies seen at the clock inputs of various registers and flip-flops match the frequency generated by the oscillator. The development of an all digital phase locked loop was interesting and a great learning experience. There are many improvements and concepts that still need to be learned, but the basics of an all digital PLL implementation was covered during this project. A good lock time was achieved of 105 cycles and considerations for power were implemented in this project.
