Random Number Generators with logic gates only are popular among digital IC designers in terms of their speed compatibility and uncomplicated integration to digital platforms. To the best of our knowledge, this paper presents the first ASIC implementation of a Random Number Generator based on Fibonacci and Galois ring oscillators. Prototypes have been designed and fabricated by using HHNEC's 0.25J.lm eFlash process with a supply voltage of 2.5V. Fibonacci and Galois ring oscillators are implemented in combined configuration. A combined configuration, which consists of a Fibonacci ring oscillator with 16 inverters and a Galois ring oscillator with 32 inverters, occupies 0.0048mm 2 and dissipates 2.5mW of power which is quite small compared to other well-known random number generators based on digital circuitry. IC design level experiences, measurements, analysis of measurements and statis tical test results are also demonstrated. Furthermore, we propose to use several of these oscillators in an xored configuration, in order to speed up and improve the quality of the generated bit stream. We could achieve fulfilled test results from NIST 800-22 test suit after Von Neumann corrector for 7 xored Fibonacci and Galois ring oscillators with a sampling frequency of 125MHz and 31.25Mbps throughput. In addition, increasing the number of xored Fibonacci and Galois ring oscillators from 7 to 8 also fulfills the tests of NIST 800-22 at the same sampling frequencyhowever, without any further post processing. Thus, 125Mbps of throughput, which is the highest data rate to date with fulfilled test results, could be obtained.

The Internet of Bio-NanoThings (IoBNT) concept envisions the connection between biological cells and the Internet. The ultimate goal of IoBNT is to catalyze a revolution in biomedical technologies through advances in molecular communication, integrated systems, bio-nanosensors and synthetic biology to improve human health and quality of life. In this paper, an application of IoBNT called PANACEA (a solution or remedy for all difficulties or diseases in Latin) is presented as a solution for an end-to-end design towards realizing the IoBNT for the first time in the literature. The architecture of PANACEA is tailored to focus on diagnosis and therapy of infectious diseases. In PANACEA, to detect the communication within the cells of the body to deduce infection level, a submilimeter implantable bio-electronic device, a Bio-NanoThing, is proposed. BNT can transmit the detected infection data remotely to a wearable hub/gateway outside of the body. The hub can use mobile devices and the backbone network such as Internet or cellular systems to reach the healthcare providers who can remotely control the BNTs. Hence, PANACEA provides a system, where sensing, actuation and computing processes are tightly coupled to provide a reliable and responsive disease detection and infection recovery system. Incorporating molecular communication and conventional networks brings many challenges that are attacked in various fronts such as circuit and biosensor design, communications engineering, with novel solutions presented in this paper, accompanied with simulation results.
