Abstract

See full text

Apparatus and methods are disclosed that utilize magnetically differential loop filter capacitor elements that are physically positioned adjacent voltage-controlled oscillator (VCO) inductor/s in the device layout of a phase locked loop (PLL) circuit. Such a PLL circuit may be employed, for example, to produce a PLL output signal for RF receivers, RF transmitters, RF transceivers and any other type of circuit configured to utilize a PLL output signal having a phase that is based on the phase of an input signal.
