Unified Analog PUF and TRNG Based on Current-Steering DAC and VCO
IEEE Transactions on Very Large Scale Integration (vlsi) Systems, 2020This work presents a unified weak physical unclonable function (PUF) and a true random number generator (TRNG) based on the current-steering digital-to-analog converter (DAC) and ring voltage-controlled oscillator (VCO).

Journal of Network and Computer Applications, 2008
When customers with different membership and position use computers as in the university network systems, it often takes much time and efforts for them to cope with the change of the system management. This is because the requirements for the respective computer usage are different in the network and security policies.

Frequency Interleaving DAC (FI-DAC)
2019In the previous chapters, time-domain DAC interleaving concepts were covered. In this chapter, a frequency domain concept is proposed. The FI-DAC concept enhances the bandwidth of DACs by using an analog processing system consisting of mixers, filters and a combiner.
