Abstract: A True Random Number Generator circuit compatible with all chip manufacturing technologies including CMOS, using the different types of multiple entropy sources to enhance the different parameters of a single circuit which generates the random numbers, wherein the output of a preceding entropy source affects the entropy of the succeeding entropy source. The entropy sources include metastability supporting ring oscillator, chaos circuit, sampling jitter etc., and even more number of entropy sources. The chaos source controls the oscillation frequency of the ring oscillator and the ring oscillator's output is sampled using an independent clock source with jitter. The multiple cores of TRNGs provides up to hundreds of Gbps rate for random numbers and may form an essential component of next generation of secure hardware and communication systems.

Abstract: A new class of passive modulators is described herein which can be manufactured using a standard CMOS or any other IC design technology. The proposed mm-wave modulator exhibits both phase and amplitude modulation, which can be combined to make a polar modulator using a single passive structure. The proposed modulators described herein have an excellent linearity and have good power handling capability compared to the active class of modulators.
