Title: Phase locked loop and frequency synthesizer having the same
Inventor: YAMAMORI MANABU
IPC: H03L7/183
Filed: 1999-11-22
Abstract: PROBLEM TO BE SOLVED: To provide a phase locked loop that can ensure a stable operation even when the frequency division number of a frequency divider is changed and to provide a frequency synthesizer having the loop. SOLUTION: When an N-value data latch circuit 6 receives N-value data denoting a frequency division number, a frequency divider 5 multiplies the output signal of a VCO 4 by (1/N) and a memory 7 outputs a voltage VC stored in an address corresponding to the frequency division number N. A charge pump current control circuit 8 whose resistor 11 receives the voltage VC controls a current outputted from the charge pump 2 so that a phase difference - current conversion gain Kp of the charge pump 2 is multiplied by (N/NR) when the frequency division number is NR. Thus, even when the frequency division number is increased to M-fold, since the phase difference - current conversion gain Kp is also multiplied by M based on the data stored in the memory 7, an open loop gain A(s) is not fluctuated. Since the open loop gain A(s) is not fluctuated, no phase margin is fluctuated and the stability of the operation of the PLL is ensured.
