Abstract

An oscillator system is disclosed and includes an oscillator circuit having a differential output producing a differential output signal thereat having a frequency that is a function of an input voltage. The oscillator system further includes an output buffer coupled to the differential output of the oscillator circuit. The output buffer includes an inductive voltage divider circuit configured to weaken a loading at the oscillator differential output and it increases the output power.
