摘要： A pulse radar receiver includes a power splitter configured to split a transmit (TX) trigger signal for generating a TX pulse, a phase-locked loop (PLL) configured to receive a division ratio and the TX trigger signal split by the power splitter, and generate a sampling frequency, and a sampler configured to sample a reflected wave received through an RX antenna, according to the sampling frequency generated by the PLL. Accordingly, it is possible to provide a high distance resolution by generating a sampling frequency with a difference from a TX pulse to sample a reflected wave received through an RX antenna. Thus, it is possible to overcome a limitation in the distance resolution due to the pulse width and to measure a minute movement at a short distance. Therefore, the pulse radar receiver is applicable to high range resolution radar applications such as a living body measuring radar.

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.
