摘要： A frequency mixing circuit and a frequency mixing method. The frequency mixing circuit includes first and second differential amplifiers, a subtracter and a mixer. The first differential amplifier amplifies a first pair of input signals having a first frequency to generate a first differential signal. The second differential amplifier amplifies a second pair of input signals having the first frequency orthogonal to the first pair input signals to generate a second differential signal. The subtracter subtracts the second differential signal from the first differential signal. The mixer mixes the subtracted signal with a first and second pairs of drive signals having a second frequency orthogonal to each other, in a sub-harmonic double balanced mixing mode, so that the mixer generates a pair of output signals orthogonal to each other without secondary harmonics.

摘要： A capacitance multiplier includes a self-biasing active load for generating a stable bias voltage without a separate current bias. In addition, the capacitance multiplier includes a cascode load within a multiplying section for increasing the output resistance and in turn the charging/discharging efficiency. Furthermore, the capacitance multiplier is implemented with a plurality of multiplying paths to reduce effects of noise for more stable generation of the multiplied capacitance.

摘要： Provided is a circuit for compensating for the declination of balanced impedance elements and a frequency mixer. The compensation circuit compensates for a difference between impedance measured at first and second impedance elements, and comprises first and second impedance circuits. The first impedance circuit transforms a first impedance value into a fine impedance value having 2n steps in response to n lower bits of a control signal having k bits. The second impedance circuit transforms a second impedance value into a coarse impedance value having 2m steps in response to m upper bits of the control signal. The first and second impedance values are measured at the first and second impedance elements, respectively, and k is equal to m plus n. The impedance difference between the impedance elements is linearly regulated.
