Abstract: An electronic circuit to cancel the input bias currents of a differential amplifier over most of the common-mode input voltage range is provided. The circuit includes an arrangement of transistors, current mirror and current sources to track the input bias currents of the differential amplifier even when the common-mode voltage is within at least 0.2 volts of the supply rail voltage level. The input bias cancellation currents are generated by tracking the input bias currents and injected into the differential amplifier inputs to cancel the input bias currents. The circuit includes a bootstrap loop to track the input bias currents when the common-mode voltage fluctuates.

Abstract: The present invention provides an electronic device manufacturing method and an electronic device which make it possible to reduce the waste of materials and the number of manufacturing steps required. Electronic devices are manufactured via a process including creating a collective substrate, in which a plurality of substrates corresponding to the electronic devices being manufactured are connected in the form of a matrix, mounting electronic parts on the upper surface of the collective substrate, forming a solidified resin layer using a vacuum printing method so that said resin layer covers the upper surface of the collective substrate on which the aforementioned parts have been mounted, or an intermediate layer consisting of an insulating elastic material, and so that said resin layer covers the electronic parts, and separating the collective substrate on which the above-mentioned resin layer has been formed into individual substrates.

Abstract: Methods and apparatus for beaming power from one location to another are provided. Energy is used to power one or more lasers to provide a coherent, wide-aperture beam, which is directed to the receiving platform. Photovoltaic cells on the receiving platform convert energy of the laser beam into electrical energy. Receiving platforms are provided that take advantage of the higher energy density in the laser beam.

Abstract: A system suitable for use in a speech recognition system or other voice processing system extracts features related to the frequency and amplitude characteristics of an input speech signal using a plurality of complex band pass filters by processing the outputs of adjacent bandpass filters.
