—A digital random return-to-zero technique is presented to improve the dynamic performance of current-steering digital-to-analog converters (DACs). To demonstrate the proposed technique, a CMOS 8-bit 1.6-GS/s DAC was fabricated in a 90-nm CMOS technology. The DAC achieves a spurious-free dynamic range better than 60 dB for a sine-wave input up to 460 MHz(More)
The performance of an automated conflict resolution algorithm was investigated in terms of its sensitivity to specific airspace regions and increased traffic demand. The algorithm is envisioned as part of an automated separation assurance function in a future air traffic control system. It was tested in a non-real-time simulation of current-day and heavily(More)
