A CMOS centric phase array radar architecture is proposed for long range detection with a high angular resolution and short range with a large field of view at once. And one channel transceiver is implemented in a 65nm CMOS technology and patch array antenna also fabricated on LTCC (Low Temperature Co-fired Ceramic) substrate for small form factor, low(More)
A single-chip impulse radar transceiver is presented. A high-resolution, enhanced SNR and controllability are achieved with a proposed architecture. By controlling timing between the transmit (TX) pulse and sampling clock of the receiver, echo pulses from targets are received and recovered. The TX pulse can adjust its spectrum occupancy by changing impulse(More)
This paper explores the use of interactive communication and dialogic relationship building strategies on political campaign Web sites. In contrast to presidential races that often feature substantially more sophisticated campaign Web sites, congressional candidates’ ability and willingness to use the Web as an electioneering tool has varied greatly. The(More)
A current reuse cross-coupling transformer-based VCO with low phase noise and low power consumption was implemented in 0.13 mum CMOS. The oscillation frequency was tuned from 4.6 GHz to 6 GHz (26% tuning range) using two different-sized varactor that adjusted fine and coarse tuning. The measured phase noise at 5.0 GHz was -124 dBc/Hz (1 MHz offset) and(More)

The Middle East respiratory syndrome coronavirus (MERS-CoV) outbreak in South Korea in 2015 has drawn public attention regarding the legal regulation of infectious disease control in Korea. This paper discusses the interpretive and legislative concerns regarding the Infectious Disease Prevention and Control Act, its ordinance and enforcement regulations, as(More)
