Abstract
The present invention relates to a broadband voltage controlled oscillator and a method for generating a broadband oscillation frequency; and, more particularly, to a broadband voltage controlled oscillator and a method for generating a broadband oscillation frequency capable of operating over a wide frequency band by including a weighted current cell to select two frequency band modes, generating various levels of total 64 oscillation frequencies by including a variable frequency tank and a capacitor bank, and further facilitating adjustment of the total 64 oscillation frequencies distributed over the wide frequency band by including a control signal generator for generating control signals each of which is applied to the weighted current cell, the variable frequency tank and the capacitor bank by a BDD (Binary Decision Diagram) technique.
