A Colpitts oscillator is a type of LC oscillator used to generate sinusoidal signals in analog circuits. Its basic circuit consists of a transistor (BJT or FET) for amplification, an inductor (L), and two capacitors (C_1) and (C_2) forming a capacitive voltage divider in the feedback network. The junction of the two capacitors is connected to the transistor’s input (base or gate), while the inductor is connected in series with ______ ______ ___ _________ ___ ______ _________ _______ ________ ___ ______.
