    摘要： Disclosed is a variable inductance applying device using a variable capacitor, and a variable frequency generating device thereof. The variable inductance applying device includes: a first inductor whose both terminals are connected to an inductance applying terminal applying inductance to an external circuit; a second inductor inductively coupled to the first inductor; and a variable capacitor connected to both terminals of the second inductor, which varies inductance from the inductance applying terminal by changing capacitance. Therefore, the inductance to be applied to the external circuit can be varied by changing the capacitance of the variable capacitor. Since the variable capacitor rarely contains a resistance component, energy loss due to the resistance component hardly occurs. As a result, the variable inductance applying device has a high value of Q.

    摘要： An integrated circuit having integrated inductors includes at least one pair of transistors, and at least one inductor group which includes a pair of inductors coupled to the at least one pair of the transistor, respectively. The pair of the inductors form a spiral shape on a plane and the inductors arranged symmetrically to each other. Magnetic fluxes, which are generated by current flows along the inductors of the at least one inductor group, are formed in a direction to mutually intensify the magnetic fluxes according to differential signals applied to the at least one transistors from outside. Accordingly, high inductance and high quality factor can be attained owing to the positive magnetic coupling of the inductors.

    摘要： A radio frequency (RF) receiver and a method of receiving an RF signal are provided. The RF receiver includes a low-noise amplifying unit which amplifies a received signal while restricting out-of-band interference of the received signal, a sampling unit which performs sampling to convert the amplified signal to a discrete time domain signal, a frequency translation unit which down-converts the discrete time domain signal into a frequency band that enables the discrete time domain signal to be converted into a digital signal and restricts interference from a frequency within an aliasing band according to a sampling frequency, an anti-aliasing filtering unit which prevents aliasing from the down-converted signal, a clock unit which provides the sampling unit, the frequency translation unit, and the anti-aliasing filtering unit with sampling frequencies, and an analog-digital-converter which converts the converted signal into the digital signal.

    摘要： A linear mixer circuit with a current amplifier has an excellent linearity by using RF open-load and an improved current amplifier. Therefore, a voltage-current converting stage and a current-voltage converting stage in a conventional mixer circuit can be omitted. Further, by using the RF open-load and the current amplifier together, a current type input signal can be transmitted as it is, and non-linearity due to the voltage-current converting stage and the current-voltage converting stage can be prevented. Furthermore, bias current of the amplifying stage and the switching stage can be separated by using the RF open-load, so that an image frequency can be filtered by the RF open-load.
