An analytical modeling is presented for the Colpitts and Clapp voltage-controlled oscillators, from which more precise eduations are derived for calculation of oscillation freguency and small- signal negative resistance. Modeling is performed with taking into account a field- effect transistor parasitic capacitances. Finally, a comparison of start- up conditions is made for the Colpitts and Clapp oscillators verified by SPICE simulations. The derived equations assure a more accurate modeling, designing and implementing the Colpitts and Clapp voltage-controlled oscillators.
