Abstract
Certain aspects of the present disclosure provide methods and apparatus (e.g., a level shifter) for buffering an oscillating signal generated by an oscillator. One example apparatus generally includes an amplifier having a first amplification stage configured to amplify the oscillating signal generated by the oscillator and a second amplification stage configured to amplify an inverse of the oscillating signal generated by the oscillator; and a sensing circuit configured to adjust an operational bandwidth of the amplifier based on a frequency of the oscillating signal.
