| Abstract: | The paper examines
the effect of an additional derivative control signal (ADCS) on the steady
state phase jitter characteristics of first and second order digital phase
locked loops (DPLLs) having a finite level quantizer. It has been shown that
the ADCS reduces the steady state phase jitter variance particularly when the
DPLL gain parameters are high and the input signal has large frequency
detuning. Further, a prefixed amount of SSPJ variance can be achieved in
presence of the ADCS for a loop with a quantizer having lesser number of
levels. The simulation results obtained have been qualitatively interpreted. |
