    摘要: An integrated circuit (IC) uses a current source (420) coupled to means (460) for current-to voltage conversion to reject the unwanted high voltage signal (VHV,) and detect the wanted small voltage signal (VSENSE). In particular, the current source produces mirrored currents (I2, I3) proportional to the high voltage signal, while the means for converting current to-voltage rejects the common-mode current ( I2-I3) when there is no small signal voltage flowing through a sensing resistor (414). On the other hand, when the small signal voltage exists, a current flows across the sensing resistor and disturbs the balance of the current mirror. As a result, the common mode no longer exists and the means for converting current-to-voltage converts and amplifies this small signal current into a voltage (VOUT) proportional to the small voltage signal.

    摘要: An integrated circuit parallel multiplication circuit delivers both natural multiplication products and polynomial products with coefficients over GF(2). The parallel multiplier hardware architecture ( Fig. 3 ) arranges the addition of partial products (Pi, j) so that it begins in a first group of adder stages (23) that perform additions without receiving any carry terms as inputs, and so that addition of the carry terms (e k+1 ) is deferred until a second group of adder stages (29) is arranged to follow the first group. This intentional arrangement of the adders into two separate groups allows both the polynomial product (d k ) to be extracted from the results (s k ) of the first group of additions, and the natural product (c k ) to be extracted from the results of the second group of additions.

    摘要: A power-on-reset circuit includes a first charging stage (162) for building up a charge during power up. The rising voltage of the first charging stage is sensed and used to control means (122) for charging up a second charging stage (164). When the second charging stage reaches a first voltage level, a circuit (130) is tripped to pull the potential of the first to ground. The grounding of the first charging stage (162) is fed back to the charging means (122) which shuts off its power burning components and maintains the first voltage level at the second charging stage (164).

    摘要: A registration mark, in integrated circuit technology, is formed by a first etching of a first mask layer (205) on top of an ONO stack (120, 125, 130) . After a first region (210) is doped, a second etching occurs at first etching sites (305) in the uppermost oxide layer (130) of the ONO stack forming a first alignment artifact (510b) . A second mask layer (405) is applied after removing the first mask layer. A second doping (515) occurs at second mask layer etching sites (510a) to maintain clearance between the two doped regions (210, 515) within active areas and provide an overlap (520) of the two doped regions in a frame area. At the overlap of the two wells, further etchings remove remaining layers of the ONO stack and remove silicon (605) from the upper most layer of the semiconductor forming a second registration mark (710) , which may be covered by a protective layer (720) .

    摘要: A method of fabricating an electronic device and the resulting electronic device. The method includes forming a gate oxide on an uppermost side of a silicon-on-insulator substrate; forming a first polysilicon layer over the gate oxide; and forming a first silicon dioxide layer over the first polysilicon layer. A first silicon nitride layer is then formed over the first silicon dioxide layer followed by a second silicon dioxide layer. Shallow trenches are etched through all preceding dielectric layers and into the SOI substrate. The etched trenches are filled with another dielectric layer (e.g., silicon dioxide) and planarized. Each of the preceding dielectric layers are removed, leaving an uppermost sidewall area of the dielectric layer exposed for contact with a later-applied polysilicon gate area. Formation of the sidewall area assures a full-field oxide thickness thereby producing a device with a reduced-electric field and a reduced capacitance between gate and drift regions.
