    摘要: In bulk channel charge coupled devices the nonlinearity in the input characteristic caused by varactor effects is removed by moving the potential well in which the charge packets are generated below the input electrode to the surface where the center of electrical charge is substantially independent of the value of the charge. Said shift can be obtained by external means, for example an extra d.c. voltage at the input electrode, or by internal means, for example a thicker oxide below the input electrode.

    摘要: A submount for arranging electronic components on a substrate is provided. The submount comprises a head member and at least one substrate-engaging member protruding from the head member. The head member comprises at least two, from each other isolated, electrically conductive portions, where each electrically conductive portion comprises a component contact, adapted for connection of electronic components thereto, and a substrate contact on arranged on said substrate side, adapted for bringing said electrically conductive portions in contact with a circuitry comprised in said substrate. The submount of the present invention may be used to attach electronic components, such as light-emitting diodes, to a textile substrate, without the need for soldering the electronic component directly on the substrate.

    摘要: A display device has an array of display elements (2) each driven by an input provided on a data conductor (6). These inputs are generated by data conductor addressing circuitry (9) which has a plurality of controllable driver circuits (32,34,40), each for providing an input to an associated data conductor. The number of controllable driver circuits is at least one greater than the number required for providing data to all data conductors. A reference driver circuit (30) is used for calibrating at least one of the controllable driver circuits whilst the other controllable driver circuits provide inputs to the data conductors. This provides a reduction in the spread of driver circuit outputs by calibration of the driver circuits using a reference driver circuit.

    摘要: A third-order all-pass network for a delay circuit is formed by four coupled transconductors (G.sub.10 to G.sub.13) which are each represented by two transistors whose bases constitute the inputs and whose collectors constitute the outputs of the transconductor. A first input of these transconductors (G.sub.10 to G.sub.13) is connected to ground (3). Between the second inputs (25,26) of the first transconductor (G.sub.10) and the second transconductor (G.sub.11) a first capacitor (C.sub.1) is arranged, between the second inputs (26,27) of the second transconductor (G.sub.11) and the third transconductor (G.sub.12) a second capacitor (C2) is arranged, and between the second inputs (27,28) of the third transconductor (G.sub.12) and the fourth transconductor (G.sub.13) and a third capacitor (C3) is arranged. Further, a fourth capacitor (C4) is arranged between the second inputs (25,27) of the first transconductor (G.sub.10) and the third transconductor (G.sub.12), a fifth capacitor (C5) is arranged between the second inputs (26,28) of the second transconductor (G.sub.11) and the fourth transconductor (G.sub.13), and a sixth capacitor (C6) is arranged between the second inputs (25,28) of the first transconductor (G.sub.10) and the fourth transconductor (G.sub.13). The third (C3), fourth (C4) and sixth (C6) capacitors reduce resonance tendencies of the circuit and consequent resonance rise symptoms as a result of parasitic effects.
