Single-phase inverters need large bulk DC link electrolyte capacitors which reduce the life time of the converter circuit. Furthermore, there is a safety need for low input voltage in photovoltaic (PV) residential applications. A new cascaded power-decoupling topology is proposed in this paper with film capacitors and high step-up ratio. The topology is based on cascaded double boost; the output of...
The two-stage amplifier design has been well studied in past decades. Many high performance amplifiers have also been proposed by various researchers. However, it is hard to find a standard design flow for an amplifier. Hence, in this paper, we propose a standard flow to design a two-stage amplifier. By applying the standard design flow, an analog circuit designer can speed up the whole design procedure...
This paper presents a power management circuit implementing a Synchronous Electric Charge Extraction on piezoelectric energy harvesters based on a flyback architecture.

There are no further special requirements and the mentioned provisions in the presentation booths, i.e. a power plug, a table, and a pin wall, are sufficient.
In this work, the design of a 94GHz rotary traveling wave oscillator (RTWO) is presented. The oscillator targets mm-Wave transceivers for biomedical imaging applications. A design procedure to minimize the total power consumption is presented. Using this proposed procedure, a 4 section RTWO is designed in a 65nm CMOS technology. The oscillator consumes 80mA (including buffers) from a 1V supply, and...
The effects of inductive coupling among TSVs within large TSV arrays are investigated in this paper. A comparison of the equivalent inductance of a paired TSV model and arrayed TSV macromodel is presented for three TSV distribution topologies, grouped, lined, and uniform, within the power network. Modified closed-form expressions are proposed to determine the equivalent inductance of a TSV in these...
Current physics-based synthesis techniques tend to synthesize the interaction between different functional elements of a sound generator by treating it as a single system. However, when dealing with the physical modeling of complex sound generators this choice raises questions about the resulting flexibility of the adopted synthesis strategy. One way to overcome this problem is to approach it by individually...
Compared with conventional power plants, wind power plants (WPP) have their own characteristic, which are more vulnerable to transient overvoltages. Transient overvoltages may contribute to insulation failures of step-up transformers. In WPPs, the transient overvoltage is mainly caused by switching operations of vacuum circuit breakers. In this paper, suitable models for the simulation of transient...
