    摘要： Provided are an on-chip balun, a transceiver using the on-chip balun, and a method for fabricating the on-chip balun. The on-chip balun includes: a first metal winding including a port grounded and a port to which an unbalanced signal is input; a second winding outputting an induced current generated by the first metal winding as two signals having about equal intensity and a phase difference of about 180°; and a ground shield positioned between the first and second metal windings and having a symmetric structure so as to generate a symmetric parasitic capacitance between the ground shield and the second metal winding. The ground shield can be inserted between the first and second metal windings to remove an asymmetrical parasitic capacitance so as to reduce a phase imbalance and a gain imbalance of an output value of the second metal winding. As a result, a highly balanced on-chip balun can be fabricated.

    摘要： A variable degeneration impedance supply circuit, including: two alternatively connected transistors; a capacitor circuit having a predetermined capacitance and serially connecting output terminals of the two transistors; and a switch for controlling on/off state between the capacitor circuit and the output terminal, according to a predetermined first control signal. The circuit further includes: at least one sub capacitor circuit arrayed in parallel to the capacitor circuit for serially connecting the output terminals of the two transistors; and at least one sub switch for controlling on/off state between the sub capacitor circuit and the output terminal, according to a predetermined control signal. Therefore, the magnitude of a degeneration impedance can be varied by controlling degeneration capacitance. Moreover, the variable degeneration impedance supply circuit can be advantageously applied to a voltage controlled oscillation circuit and a frequency divider circuit.
