    摘要： A track-and-hold circuit includes a bootstrapped clock generator and a track-and-hold unit. The bootstrapped clock generator receives an input voltage signal and generates a sampling control signal having a voltage level lower than or equal to a level of a power supply voltage by maintaining an initial level of a boost capacitor voltage at a level lower than the level of the power supply voltage. The boost capacitor voltage is a voltage that is charged across a boost capacitor included in the bootstrapped clock generator and the sampling control signal is generated based on a clock signal. The track-and-hold unit samples and holds the input voltage signal in response to the sampling control signal to generate a sampled signal.

    摘要： An RF receiver and an RF receiving method are provided using a baseband signal in which a DC offset is removed. In the RF receiver, a noise phase removing unit generates a phase controlled local signal PLOQ in which a phase of a Q signal of a local signal LOQ is controlled, by synthesizing a received RF signal RXIN and the Q signal of the local signal LOQ. A down converter generates a signal in which a DC offset from noise introduced into the received RF signal RXIN is removed, when synthesizing the received RF signal RXIN and the phase controlled local signal PLOQ for frequency-down conversion.

    摘要： Provided is a mixer including: an amplifier amplifying an input signal using at least one amplifier element; a mixing unit mixing the input signal amplified by the amplifier with a local oscillator signal output from a local oscillator. The mixing unit includes at least one pair of switching elements switching the amplifier, and the switching elements are MOSFETs having gates and body nodes to which a same local oscillator signal is applied. Thus, a time required for turning on the switching elements can be reduced, and 1/f noise is also reduced. Also, an overdrive voltage can be increased with respect to local oscillator signals having an identical intensity. Thus, a relatively low voltage operation can be performed.

    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.
