Abstract
A filter couples an output of a phase detector to an input of a voltage controlled oscillator. The filter has a first capacitor and a switch capacitor resistor that is in series with the first capacitor, between the first capacitor and the output of the phase detector. The switch capacitor resistor is to display a resistance that is obtained by switching back and forth a second capacitor to the first capacitor and to the phase detector output. Other embodiments are also described and claimed.
