ABSTRACT:
An amplitude control circuit (100) can include a peak level detect circuit (102) that generates a peak voltage signal (Vpeak′) based on a peak level of signal Xosc. An amplitude bias control circuit (104) can generate a bias voltage Vbc that can correspond to a peak amplitude of a received oscillator signal Xosc, and can change according to variations in a transistor threshold voltage due to process, operating conditions and voltage.
