Abstract
A voltage controlled oscillator (VCO) for generating a clock of a 50% duty includes a VCO unit and a duty correction unit. The VCO unit generates first and second signals having a 180° phase difference to each other with an oscillation frequency according to a control voltage to output the first and second signals through first and second oscillation output terminals. The duty correction unit generates a clock signal of a 50% duty according to the first and second signals through the first and second oscillation terminals.
