Abstract
An integrated circuit includes an inductor-capacitor (LC) tank circuit coupled with a feedback loop. The LC tank circuit is configured to output an output signal having a peak voltage that is substantially equal to a direct current (DC) voltage level plus an amplitude. The feedback loop is capable of determining if the peak voltage of the output signal falls within a range between a first voltage level and a second voltage level for adjusting the amplitude of the output signal.
