The design of a rail-to-rail micropower comparator in CMOS technology is described. The circuit is intended for implantable biomedical devices powered by batteries, with a total consumption of 500nA and operation up to supply voltages of 2V. This cell, currently being fabricated, has a core die area of 0.27 mm2 on a 2.4###m standard analog CMOS technology with a 0.85V nominal threshold voltage....

A universal BiCMOS low-voltage-swing transceiver (driverlreceiver) with low on-chip power consumption is reported. Operating at 3.3V, it can drivekeceive low-voltageswing signals with termination voltages ranging from SV down to 2V without using any external reference voltages.

The experimental and theoretical adiabatic ionization energies (IEs) of the rhodium-holmium bimetallic clusters RhHo(2)O(n) (n=0-2) have been determined using photoionization efficiency spectroscopy and density functional theory (DFT) calculations. Both sets of data show the IE of RhHo(2)O to be significantly lower than the values for RhHo(2) and RhHo(2)O(2), which are found to be similar. This...

We report a joint experimental and theoretical study on the structures of a series of gold clusters doped with a sulfur atom, Au(x)S(-) (x = 2-5). Well-resolved photoelectron spectra are obtained and compared with theoretical results calculated using several density functional methods to elucidate the structures and bonding of Au(x)S(-) (x = 2-5). Au2S(-) is found to have an asymmetric linear g...

OBJECTIVE The aim of this study was to determine the microtensile bond strength to root dentin of AH Plus™ and EndoREZ® with Clearfil Liner Bond 2V and Optibond Solo™ Plus adhesive systems. STUDY DESIGN The coronal and middle thirds of six single rooted bovine teeth was split longitudinally in a mesio-distal direction. The two halves were joined with AH Plus or EndoREZ, with and without the u...

Alloys based on the near-equiatomic FeCo offer exceptional magnetic properties. The equiatomic alloy was ‘invented’ in 1929, it offers a saturation hardly lower than that of the maximum obtained for Fe-0.35Co, with higher permeability and a lower coercivity than the latter. However, this alloy remained without industrial application, mainly because of its extreme brittleness. Only with the addi...

In this paper, wire electric discharge machining (WEDM) of Titanium alloy (Ti-4.5Al-2V) is studied. In WEDM, the prime objective in cutting operation is to achieve the highest possible cutting speed along with desirable surface finish without sacrificing productivity. It is evident that a high material removal rate and a very good surface finish can never be achieved simultaneously in WEDM. Sel...
