Shift Register Based MPCG Architecture The architecture of a shift register based MPCG is shown in Fig.2(a). It consists of a divide-by-N followed by a D-FlipFlop (DFF) chain with N DFFs1. In the shift register MPCG, a reference clock generated by a VCO, CLKref, with a frequency of N·f, is fed into the divide-by-N and the DFF chain.
