摘要： A voltage sensing module for an integrated circuit (IC) that supports operation at a plurality of different voltage levels includes a voltage generation module that generates first and second voltages based on an operating voltage level of the IC. A comparing module receives the first and second voltages and generates a voltage determination signal based on the first and second signals. The voltage determination signal selectively configures an input/output I/O pad of the IC.

摘要： A pipelined analog to digital converter comprises N stages, wherein N is an integer greater than one. A sample and integrate circuit communicates with at least two stages of the N stages. The sample and integrate circuit selectively samples a first voltage input to one of the at least two stages while integrating a difference between a sampled second voltage input of another one of the at least two stages and a second reference voltage to generate a second residue. The sample and integrate circuit selectively integrates a difference between the sampled first voltage and a first reference voltage to generate a first residue while sampling a second voltage input.

摘要： As part of a photographic film, a backing antistatic layer is coated at a pH of 3 to 12 with an auxiliary layer consisting essentially of at least one crosslinkable conductive polymer and a crosslinking agent for the conductive polymer dispersed in a binder, e.g., gelatin, to conduct the antistatic properties from the antistatic underlayer to the surface of the backing layer. The crosslinkable conductive polymer and crosslinking agent can be present in separate layers on the backing layer. The film is useful in the areas of graphic arts, printing, medical and information systems.

摘要： A multistage analog circuit for independently controlling a bias current in each stage of the multistage analog circuit having an input stage, an intermediate stage, and an output stage, includes a first current source which controls the input stage of the circuit, a second current source which controls the intermediate stage of the circuit, and a third current source which controls the output stage of the circuit. The bias current in each stage of the circuit is set by the first, second, and third current sources. An output voltage of the circuit is capable of remaining the same when the first current source is changed to affect an input transconductance of the circuit.
