    摘要: An apparatus and method for removing an interference signal using a selective frequency phase converter are disclosed. The apparatus for removing an interference signal using a selective frequency phase converter includes: a first phase converter configured to convert a phase of a received RF signal to differentially output first and second signals having a phase difference of 180° from each other; a second phase converter configured to receive the first signal and selectively convert the phase of a particular frequency band; a third phase converter configured to receive the second signal and selectively convert the phase of a particular frequency band; a timing controller configured to correct a signal delay time between the output from the second phase converter and that of the third phase converter; and an adder configured to add an output from the second phase converter and an output from the third phase converter, wherein the second and third phase converters phase-convert the first and second signals such that the phases of the signals of the particular frequency bands do not have a phase difference of 180° from each other.

    摘要: A coplanar waveguide CPW using multi-layer interconnection CMOS technology is provided. In the CPW including an interlayer insulator disposed on a substrate, metal multilayers disposed on the interlayer insulator, and a ground line-a signal line-a ground line formed of an uppermost metal layer, when a ground line of a lowermost layer is connected to the ground line of the uppermost layer, intermediate metal layers are designed to gradually increase or decrease in width, or to be uneven so as to maximize an area where an ultra-high frequency spreads, thereby minimizing CPW loss and maximizing a slow wave effect. As a result, it is possible to improve performance of an ultra-high frequency circuit and miniaturize the circuit.
