This paper presents a new tool titled "Param2bode" for dynamic performance analysis of compensated three-stage amplifiers. It adjusts the parameters while observing the effects on dynamic performance in real time. Param2bode is based on equations generated automatically using techniques from symbolic analysis. We will give details concerning the followed steps of configuration and use of...
This paper presents a new method to improve analog design automation and thus design reuse. A top-down constraint driven methodology is applied to design complex analog system. This approach formulates the design problem as a multi objective optimization problem (MOOP). In the last decades optimization has been introduced in the field of analog design. Nevertheless, the knowledge needed to build an...
In this article, we present a new method to improve analog design automation and design reuse. A top-down constraint driven methodology is applied to design complex analog system. This approach formulates the design problem as a multi objective optimization problem (MOOP). As the knowledge needed to build an optimization problem dedicated to an analog circuit is still out of reach of designers, our...
. We studied a new kind of W/O emulsions based on a lyotropic liquid crystal as the aqueous droplet phase. The cholesteric phase, a solution hydroxypropyl cellulose in water was dispersed in the continuous oil matrix, paraffin oil or heptane. We made a specific choice of surfactant in order to impose director anchoring conditions at the oil-water interface and orient the liquid crystal inside the...
Six model polydimethylsiloxane (PDMS) networks were obtained by hydrosilation of a difunctional vinyl-terminated PDMS prepolymer with a SiH containing crosslinker. Viscoelastic experiments were performed in order to study the influence of molecular parameters on the dynamic properties around the sol-gel threshold. Critical parameters were determined close to and above the sol-gel threshold. Our results...
Five model polydimethylsiloxane (PDMS) networks were obtained by hydrosilation of a difunctional vinyl-terminated PDMS prepolymer with a SiH containing crosslinker. Viscoelastic experiments were performed in order to study the influence of molecular parameters on the dynamic properties at the sol–gel threshold. The results suggest that the critical exponents are not universal and depend on the chemical...
