Patent number: 6556043Abstract: A programmable logic circuit is provided that solves glitch problems associated with asynchronous logic operations associated with conventional look-up tables by utilizing a preset dominant transparent latch element to replace a conventional look-up table. Since latch elements are normally present in programmable logic circuits (e.g., FPGAs) no additional circuitry is necessary to implement the approach of the present invention. In one exemplary embodiment, an FPGA is provided which includes an array of programmable latch elements, and an array of programmable flip-flop elements generating flip-flop output signals. One or more of the latch elements are programmed to form a preset dominant transparent latch (PDTL) such that the data signals are coupled to the data inputs and preset inputs of the latch. In this manner, the latch operates to replace conventional look-up tables by operating as a primitive OR or NOR gate to generate a desired output.Type: GrantFiled: July 17, 2001Date of Patent: April 29, 2003Assignee: International Business Machines CorporationInventor: Enrique Garcia

Patent number: 6246726Abstract: To exchange a digital data input stream, a transmitter sends the digital data input stream to a receiver, and the receiver sequentially divides the stream into different interleaved substreams and later combines the substreams to provide an output including the original digital data input stream. The original digital data input stream includes multiple subgroups of data, such as bytes. Each subgroup is stored in a selected buffer of the receiver. Buffers are selected in a predetermined order of rotation to store sequentially received subgroups. Thus, each buffer receives subgroups in a defined order. Later, each buffer outputs its stored subgroups in the same order as received. A data assembler assembles the subgroups output by the various buffers, reconstructing the original digital input stream.Type: GrantFiled: February 25, 2000Date of Patent: June 12, 2001Assignee: International Business Machines CorporationInventors: Enrique Garcia, Gregg Steven Lucas, Juan Antonio Yanes

Patent number: 6191404Abstract: A charge-coupled imaging device (FIG. 3) is thinned to allow for backside illumination. The device is further enhanced using ion implantation techniques to establish an electrical field (44) at the back surface, which functions to drive free electrons to potential wells generated beneath a gate structure (40) on the front surface. The device structure allows for both front side and backside illumination and is useful as a imaging device in applications where it is necessary to combine images from two different optical sources. The imaging device is particularly useful in terrestrial guidance systems (FIG. 5) where the imaging device is used to detect guide stars from a large guide star field. In such systems, the imaging device must be translated within an X-Y plane in order to cover the entire guide star field. In order to accurately know the position of the imaging device, optical fiducial marks are imaged onto a side of the imaging device opposite the side receiving the guide star photons.Type: GrantFiled: February 25, 1992Date of Patent: February 20, 2001Assignee: Hughes Danbury Optical Systems, Inc.Inventors: Richard R.

Patent number: 6084934Abstract: A data transmission system includes a sender and a receiver, both employing different clock rates and a data bus coupled between the sender and the receiver for transmitting signals therebetween. The receiver generates an enable signal from the receiver clock to control data transmission at the sender. The enable signal is a pulse generated at each rising edge of the receiver clock and corresponds to the data transfer rate of the receiver clock. A detector module, located at the sender, receives and captures the asynchronous enable signal and initiates transmission of one data byte for each pulse of the enable signal, thereby automatically adjusting the data transfer rate of the sender to the data transfer rate of the receiver.Type: GrantFiled: March 6, 1997Date of Patent: July 4, 2000Assignee: International Business Machines CorporationInventors: Enrique Garcia, Adalberto Guillermo Yanes, Juan Antonio Yanes

Patent number: 5270221Abstract: A method for fabricating thinned, back-illuminated, solid state image sensors 10 includes steps of positively doping a bottom surface 22 of a top semiconductor wafer 24, and bonding the bottom surface 22 of the top semiconductor wafer 24 to a top surface 26 of a bottom semiconductor wafer 28 with a silicon dioxide passivation layer 34 in between. The top wafer 24 is thinned and an insulating layer of silicon dioxide 36 and a polysilicon gate structure 38 are formed thereover. Individual dies 40 are then formed, which are bonded to a substrate 42 along each pixel face. The bottom semiconductor wafer layer 28 is etched away to expose the silicon dioxide passivation layer 34, which acts to protect the thinned top wafer layer 24. The dies 40 are then etched to expose bonding pads within the gate structure 38, and sized to create thinned, back-illuminated, solid state image sensors 10.Type: GrantFiled: November 5, 1992Date of Patent: December 14, 1993Assignee: Hughes Aircraft CompanyInventors: Enrique Garcia, Richard Poole, William America

Patent number: 5162251Abstract: A standard thick silicon charge-coupled device (FIG. 1A) has its pixel face mounted to a transparent, optically flat glass substrate using a thin layer of thermoset epoxy. The backside silicon of the charge-coupled device is thinned to 10 .+-.0.5 um using a two-step chemi-mechanical process. The bulk silicon is thinned to 75 um with a 700 micro-grit aluminium oxide abrasive and is then thinned and polished to 10 um using 80 nm grit colloidal silica. Access from the backside to the aluminum bonding pads (36 of FIG. 5) of the device is achieved by photolithographic patterning and reactive ion etching of the silicon above the bonding pads. The charge-coupled device is then packaged and wire-bonded in a structure which offers support for the silicon membrane and allows for unobstructed backside illumination.Type: GrantFiled: March 18, 1991Date of Patent: November 10, 1992Assignee: Hughes Danbury Optical Systems, Inc.Inventors: Richard R.
