Abstract
A high performance phase-locked loop, the device includes a phase frequency detector, a charge pump, a loop filter, a first oscillator having inverters, configured to generate a first current, a second oscillator having a scaled version of the inverters of the first oscillator, a digital to analog converter, configured to generate a second current by multiplying the first current and a frequency code, a voltage to current converter, configured to generate a third current by converting voltage output of the loop filter to current, wherein input current to the second oscillator is sum of the second current and the third current.
