Abstract
A method and a system for calibrating an input voltage of a voltage controlled oscillator and a digital interface used for calibrating the input voltage. The method includes: setting a lock detection time for tuning a signal phase; setting a lock detection voltage section; setting output frequency values at predetermine spacings; checking connection states of capacitors of the capacitor bank necessary for a lock of the output frequency values; storing information regarding the connection states of the capacitors in the output frequency values; and if one of the output frequency values is determined depending on a change of a channel, setting connection states of the capacitors according to the information regarding the connection state corresponding to the one frequency value. The capacitor bank includes: a predetermined number of capacitors having different capacitances and connected to one another in parallel; and switches connected to the capacitors in series.
