Linear ion trap frequency standards are among the most stable continuously operating frequency references and clocks. Depending on the application, they have been operated with a variety of local oscillators (LOs), including quartz ultrastable oscillators, hydrogen-masers, and cryogenic sapphire oscillators. The short-, intermediate-, and long-term stability of the frequency output is a complicated...
We present asymmetric SRAM cell design approaches to improve Read stability over conventional symmetric SRAM Cell. We show that selective threshold voltage control is more effective than adjusting transistor size for read stability improvement in an asymmetric SRAM cell. We implement statistical DC noise margin monitors and present the hardware measurement data as well as the DC/AC simulation data...
The stability and performance characteristics of static random access memories (SRAMs) are known to degrade with time due to the impact of negative and positive bias temperature instabilities (NBTI (in PFET) and PBTI (in NFET)). In this work, we provide insights into relative sensitivities of these phenomena on speed and stability of SRAM cells. Relative impact on access time, stability, and tolerability...
This paper explore the swarm intelligence stability based on stochastic diffusion search (SDS) which is capable to find rapid location of the optimal solution in the search space. Population based search mechanisms employed by Swarm Intelligence methods can suffer lack of convergence resulting in ill defined stopping criteria and loss of the best solution. Conversely, as a result of the positive feedback...
