  • -A PLL is a closed loop system that locks the phase of an output signal to an input reference signal. The term “lock” refers to a constant or zero phase difference between two signals. The components of PLL are the Phase Frequency Detector (PFD), the charge pump (CP), the low pass filter (LPF), and the voltage controlled oscillator (VCO). In which the charge pump has been modified in order to overcome the leakage current. Hence power consumption is reduced through the modified structure. All… CONTINUE READING
