Abstract :
This paper describes a digital Manchester DLL with delta-sigma modulation, and its improved version in order to expand the tracking range. We make an approximate analysis, simulation and experiment for both DLLs. We estimate transient response and RMS jitter of tracking phase error against additive white Gaussian noise. From the analysis, simulation and experiment, the transient response and the steady state RMS jitter performance agree well. The proposed DDLLs are small size, not affected by the quantization noise and realized with reasonable tracking range. It is possible to apply delta-sigma modulation to DLL for power-line communication
