    摘要: 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.

    摘要: An MIM capacitor includes a substrate, a capacitor part having a structure in which a bottom electrode, a dielectric layer and a top electrode are laminated in order, and a ground shield layer formed between the bottom electrode of the capacitor part and the substrate and connected to a predetermined ground terminal. The ground shield layer may be formed of metal or polysilicon, or a layer doped with impurities having a valence of three or five. Also, the ground shield layer has a predetermined patterned structure. Thus, it is possible to minimize power loss due to the substrate.

    摘要: A sigma-delta modulation method with low complexity is provided. To this end, in the present invention, an input signal is forwarded and an output signal is fed back to thus reduce the range of the noise transfer function of the sigma-delta modulator and to lower the frequency offset and the phase noise at low frequencies. A sigma-delta modulator for a frequency synthesizer may include one or more modulation units which are connected in series and perform a sigma-delta modulation to an input signal and a provided accumulated signal using a signal which is weighted with a feedback coefficient; and an output adder which adds an output signal from a terminal section of the modulation units and the input signal, and outputs the added signal for feedback to the modulation units.
