High-performance and low-power are the two main criteria in modern digital design. Level converters are important to transfer low voltage input swing signal among the circuits operating at different voltages to get high voltage output swing signal. Previously feedback level converters suffer from short circuit power and long propagation delay. Multi Vth level converters and multiple supply volt...

To achieve robust and stable legged locomotion in uneven terrain, animals must effectively coordinate limb swing and stance phases, which involve distinct yet coupled dynamics. Recent theoretical studies have highlighted the critical influence of swing-leg trajectory on stability, disturbance rejection, leg loading and economy of walking and running. Yet, simulations suggest that not all these ...

A universal BiCMOS low-voltage-swing transceiver (driver/receiver) with low on-chip power consumption is reported. Using a 3.3 V supply, the novel transceiver can drive/receive signals from several low-voltage-swing transceivers with termination voltages ranging from 5 V down to 2 V and frequencies well above 1 GHz. Measured results of test circuits fabricated in 0.8m BiCMOS technology are also...

A telescopic cascode opamp typically has a higher frequency capability and consumes less power than other topologies. The disadvantage of a telescopic opamp is severely limited output swing. In a conventional telescopic opamp shown in Figure 1, all transistors are biased in the saturation region. Transistors M1-M2, M7-M8 and the tail current source M9 must have at least Vds,sat to offer a good ...

This paper concerns the application of reduced order modeling techniques to power grid simulation. Swing dynamics is a complex non-linear phenomenon due to which model order reduction of these problems is intricate. A multi point linearization based model reduction technique trajectory piece-wise linearization (TPWL) method is adopted to address the problem of approximating the nonlinear term i...

Analysis of cascading outages in power systems is important for understanding why large blackouts emerge and how to prevent them. Cascading outages are complex dynamics of power systems, and one cause of them is the interaction between swing dynamics of synchronous machines and protection operation of relays and circuit breakers. This paper uses hybrid dynamical systems as a mathematical model ...

We are interested in a well-known problem in Computer Science and Economics, the Stable Marriage Problem (SM). Considering two communities in which each member has some preferences on the potential partners, the goal is to make pairs taking into account their preferences. This abstract problem has many applications. From a multiagent approach, the seminal Gale-Shapley algorithm [2] solves the S...

Arms swing during standing back somersaults relates to three different "gymnastics schools", each is considered "optimal" by its adepts. In the three cases, technical performance, elevation and safety differ. Therefore, the aim of this study was to compare the mechanical variables of three different arms swing techniques in the performance of a standing back tucked somersault. Five high-level m...

Although the mechanical function is quite clear, there is no consensus regarding the metabolic benefit of arm swing during human running. We compared the metabolic cost of running using normal arm swing with the metabolic cost of running while restricting the arms in three different ways: (1) holding the hands with the arms behind the back in a relaxed position (BACK), (2) holding the arms acro...
