Abstract :
Multi modulus prescalers based on the phase-switching technique suffer from a spur problem due to the finite phase accuracy. The spur problem is outlined and the spurs locations and magnitudes are derived. Simulations revealing the effect of this problem on integer-N and fractional-N PLL are presented.
