Patent number: 7194399Abstract: An improved hardware circuit simulation method in particular for history-dependent and cyclic operation-sensitive hardware circuits, like SOI-type hardware, checks for correct cyclic boundary conditions by performing a first run of a DC simulation with input voltage conditions belonging to CYCLE START, and by carrying out a second DC simulation with input voltage conditions belonging to CYCLE STOP. After comparing the results, e.g., comparing the node voltages, any mismatches can be determined which serve as a hint to non-compatibility with cyclic operation. Thus, the design is able to be re-designed before being simulated in vain with a great amount of work and computing time. A transient simulation can be appended for automated correction of dynamic errors.Type: GrantFiled: July 10, 2001Date of Patent: March 20, 2007Assignee: International Business Machines CorporationInventors: Karl-Eugen Kroell, Juergen Pille, Helmut Schettler

Patent number: 5744996Abstract: An integrated semiconductor circuit for reducing power consumption, employing CMOS technology in which a transistor pair can be operated stably at different supply voltages. At each supply voltage the transistors have an associated threshold voltage which can be set via the well and substrate bias voltages. The substrate of the transistor pair is connected to a substrate bias voltage generator circuit and the well is connected to a well bias voltage generator circuit. An input signal representing the level of the supply voltage sets the respective bias voltages corresponding to the level of the supply voltage. Thus, the threshold voltage of each transistor is adapted to the existing supply voltage, thereby ensuring stable operation of the transistor pair. A battery driven data processing system with the integrated semiconductor circuit can attain an approximate 100 fold extension of the operating time of the battery.Type: GrantFiled: July 17, 1995Date of Patent: April 28, 1998Assignee: International Business Machines CorporationInventors: Gunther Kotzle, Volker Kreuter, Thomas Ludwig, Helmut Schettler

Patent number: 5306866Abstract: A module containing an electronic package provides a housing for cooling and protecting the electronic package. A top metal shell and a bottom metal shell form a common cavity in which the package is embedded without touching the inner walls of the cavity. A flexible thermally conductive foil is fixed to each of the shells. The foil is adjustable to the surface of the package and is isolated from electrically conductive parts of the package. A cooling liquid fills the gaps between the metal shells and the foils. Flexible isolated circuit means connect the package to the outside of the housing, balancing means balance pressure and volume between the shells, and further means firmly hold together the housing.Type: GrantFiled: April 13, 1992Date of Patent: April 26, 1994Assignee: International Business Machines CorporationInventors: Harald W.

Patent number: 5244833Abstract: A method for making an integrated circuit chip packaging structure comprising a substrate, preferably a semiconductor base substrate, a conductive layer on said substrate in regions where connections to metallization layers of the substrate are formed, solder balls and gold bumps connected to said conductive layer in said regions of said conductive layer, and a solder stop layer on said conductive layer at least around said solder balls. The conductive layer further comprises wiring lines. Further, a method of forming the structure is disclosed which uses only two masks for providing terminals for connecting the substrate to integrated circuits and to other substrates or to the printed circuit board and wiring lines. Thus, there is a need for one less metallization layer. The method is applicable to 200 mm wafers and allows two different packaging technologies (C-4 and TAB or wire-bonding) on the same substrate. Thus, packaging of VLSI circuits is improved.Type: GrantFiled: April 11, 1991Date of Patent: September 14, 1993Assignee: International Business Machines CorporationInventors: Peter Gansauge, Volker Kreuter, Helmut Schettler

Patent number: 4967104Abstract: The present invention teaches an arrangement for increasing the output impedance of a power amplifier coupled to a capacitively loaded line during the switching of power levels by the amplifier on the line. The arrangement of the invention reduces undesired noise voltage during switching. The present invention achieves this end by using a control circuit composed of a differential amplifier which has one input fed from the junction of an impedance resistor and a transistor that simulate the power stage transistor in the power amplifier being switched. This control circuit provides control voltage outputs to power control transistors which are connected to and control the speed of the power stage transistors used to change and discharge the capcitively loaded line.Type: GrantFiled: October 2, 1989Date of Patent: October 30, 1990Assignee: International Business Machines CorporationInventors: Thomas Ludwig, Helmut Schettler, Otto M.

Patent number: 4890238Abstract: For the physical design of a very large scale integration (VSLI) chip, a method is provided to implement a high density master image that contains logic and RAMs. In a hierarchical top-down design methodology, the circuitry to be contained on the chip is logically divided into partitions that are manageable by the present automatic design systems and programs. Global wiring connection lines are from the beginning included into the design of the different individual partitions and treated there in the same way as circuits in that area. Thus, the different partitions are designed in parallel. A floor plan is established that gives the different partitions a shape in such a way that they fit together without leaving any space between the different individual partitions. The chip need no extra space for global wiring and the partitions are immediately attached to each other.Type: GrantFiled: December 15, 1987Date of Patent: December 26, 1989Assignee: International Business Machines CorporationInventors: Klaus Klein, Kurt Pollmann, Helmut Schettler, Uwe Schulz, Otto M.

Patent number: 4815113Abstract: A method for the digital slope control of the output signals of power amplifiers, as well as a power amplifier suitable for carrying out the method as described. One way of representing the actual slope value is via the number of clock pulses applied to a counter during a measuring interval which depends in its duration on the slope. Such a measuring interval is produced by applying the pulses of a ring oscillator containing one of the power amplifiers to another counter until the overflow of the latter. Another mode of representing the actual slope value consists in counting the number of pulses of the ring oscillator during a measuring interval of predetermined duration. Actual and nominal values of the slope are compared. The results of this comparison change the contents of a left/right-shift register.Type: GrantFiled: October 20, 1987Date of Patent: March 21, 1989Assignee: International Business Machines CorporationInventors: Thomas Ludwig, Helmut Schettler, Otto Wagner, Rainer Zuhlke

Patent number: 4682050Abstract: A small signal swing line driver, that generates a reduced amount of switching noise and also suppresses transients appearing on the line, is described. Specifically, the driver includes a clamp connected to the driver output to limit the maximum DC driver output level and to suppress voltage transients, e.g. reflections, spikes or the like, appearing on the driven line and caused by conditions external to the driver. The driver also contains circuitry to limit the transition times of the rising and falling edges of the driver output signal in order to reduce the amount of switching noise which is generated by the driver and thereafter coupled onto quiet lines.Type: GrantFiled: January 8, 1986Date of Patent: July 21, 1987Assignee: International Business Machines CorporationInventors: Herve L. Beranger, Gene J. Gaudenzi, Dennis C. Reedy, Helmut Schettler
