摘要： A frequency synthesizing apparatus and method for a multi-band radio frequency (RF) receiver is provided. The frequency synthesizing apparatus includes a simple circuit configuration with a single SSB mixer and thus, may synthesize six high frequency signals. Signals to be inputted into the SSB mixer include a first signal and a second signal. The first signal is generated based on a VCO and a PPF. Also, the second signal is selected from a plurality of frequency divided signals which are generated by dividing a signal generated in the VCO via a plurality of dividers.

摘要： A system and a method for self calibrating a voltage-controlled oscillator (VCO). In the system, a mode controller generates a control signal for each of an automatic band selection mode, an automatic gain tuning mode, and a phase-locking mode, from a frequency comparison result between a reference clock signal and a divided clock signal which is generated by dividing a frequency of an oscillation signal, and thereby controls the VCO, so that the VCO may generate the oscillation signal which is automatically phase-locked in a target frequency with an optimal state.

摘要： An apparatus and method of reducing a flicker noise of a CMOS amplifier is provided. In the CMOS amplifier, a load circuit is connected to a signal input circuit which includes two pairs of MOSFETs which simultaneously receive differential signals.
