New fractional phase-locked loop frequency synthesizer using a sigma-delta modulator
Original language description
The fractional frequency synthesizer is similar to the divide-by-N phase-locked loop (PLL) (divider in feedback path). However, the output frequency of the voltage-controlled oscillator (VCO) is not restricted to integral multiples of the reference signal only. Rather, it can also be locked to the fractional multiples, with the result of a substantial reduction of the frequency tuning step in the useful bandwidth of the PLL without reduction of its pass band. In this paper, the new fractional PLL frequency synthesizer with ?-? modulator is described. A complete fractional PLL was simulated and partly constructed and measured.
