摘要:
A phase locked loop PLL having a forward path and a feedback path is disclosed. A phase detector drives an oscillator in the forward path of the phase locked loop. The feedback path includes a frequency divider that connects the oscillator output to the phase detector. The phase locked loop further includes an integrator-free loop filter configured to control the oscillator. The integrator-free loop filter enables a reduction in the required PLL bandwidth without reducing the signal quality when the PLL is used as a modulator.
