Abstract
A system includes a phase locked loop (PLL), which includes a filter. The filter may include a first amplifier and a second amplifier, where a feedback current from the first amplifier and the second amplifier is based on a parallel resistance of multiple parallel feedback resistors. The feedback current may be coupled to a noninverting input of the first amplifier.
