Abstract :
A technique to improve the linearity of the frequency-voltage (f - V) characteristic and to reduce the differential tuning sensitivity, KVCO, of voltage-controlled oscillators (VCOs) is proposed. The VCO designed using the linearisation technique is tunable from 806 to 1113 MHz with a 34 tuning range and exhibits a nearly constant KVCO of 62 MHz/V over the entire frequency range.
