Abstract
A method for detection and correction of nonlinearities in radio-frequency voltage controlled oscillators provides for division of the output signal of the oscillator, direct analysis of the divided output signal by means of a counting device, conversion of the respective counter value to an equivalent voltage value, and production of a control signal with a corrected frequency response for the oscillator by logic-link the equivalent-voltage value to a predetermined nominal value.
