An amplifier with increased bandwidth by current injection and a method thereof. The amplifier includes an input stage for receiving a first input signal, a load stage coupled to the input stage for generating a first output signal, a first current source coupled to the input stage for allowing a predetermined current to flow, and a second current source, coupled to the input stage, for injecting a first current into the input stage for outputting the first output signal.

A cascode circuit in which two field effect transistors ("FET") are connected in cascode has a first FET having its source grounded, a second FET having its source connected to the drain of the first FET, and a Schottky barrier diode having an anode connected to the source of the first FET and a cathode connected to the gate of the second FET.

The present invention relates amplifiers using metal oxide semiconductor based integrated circuits. The present invention is particularly but not exclusively related to audio application mixed signal chips. The present invention provides an analog circuit for processing analog signals in an integrated circuit comprising a number of metal oxide semiconductor transistor devices, the circuit stage comprising a first said transistor device having a first oxide thickness, and a second said transistor...

Novel compounds are disclosed having useful activity as bronchodilators of improved longevity of action and reduced incidence of side effects. These compounds are described by the formula: ##EQU1## wherein R.sub.1 is a member of the class consisting of tertiary butyl and cyclobutyl, and R.sub.2 is a hydrogen or 2 to 5 carbon atom acyl radical, and pharmaceutically acceptable salts thereof. The activity of these compounds is compared to previously known bronchodilators such as 1-(3', 5'-dihydroxy...

Drugs which are suitable for such therapy in treatment of narcotic drug addiction by oral use, e.g., methadone, are formulated to prevent injection abuse through concentration of the active component in aqueous solution by incorporating in a solid dosage or tablet form of such drug an ingestible solid precipitating agent for said active component, preferably in association with at least one ingestible solid having thickening properties which causes rapid increase in viscosity upon concentration ...

This invention relates to an improvement in rotating X-ray targets involving incorporation of small quantities of boron into the molybdenum-containing base portion. 7 Claims, No Drawings

A rotating X-ray target comprised of a graphite body having brazed thereon a metal band focal track or layer in which the configuration of the surfaces of the graphite base and the metal layer corresponds to an annular segment of a spherical surface and method for preparing same.

A method for inducing increased inotropic effects of the human heart without inducing arrhythmogenic effects, but providing an antiarrhythmogenic effect therein. The method is effected by administering to mammals, including man, a compound of the formula ##STR1## wherein R is selected from the group consisting of hydrogen or ##STR2## wherein R' is selected from the group consisting of straight or branched aliphatic alkyl having 1 to 7 carbon atoms, phenyl, benzyl, and phenylethyl, wherein the ph...

Compounds of the following general formula are useful in the treatment of sickle cell anemia: ##STR1## WHEREIN EACH OF R and R.sub.1 is hydrogen, chlorine, fluorine, bromine, trifluoromethyl, hydroxy, a lower alkoxy group of from 1 to 4 carbon atoms or a straight or branched lower alkyl group of from 1 to 4 carbon atoms; R.sub.2 is hydrogen or a straight or branched lower alkyl group of from 1 to 4 carbon atoms; R.sub.3 is hydrogen or a straight or branched lower alkyl group of from 1 to 4 carbo...

Alpha-[(lower alkylamino)alkyl]-4-hydroxy-3-(alkylthio, alkylsulfinyl or alkylsulfonyl)benzenemethanols which have .beta.-adrenergic blocking activity and which are therefore useful in controlling tachycardia are prepared by reduction of the corresponding (lower alkylamino)alkyl 4-hydroxy-3-(alkylthio, alkylsulfinyl or alkylsulfonyl)phenyl ketones.
