摘要： An apparatus and method for externally managing data within an asynchronous pipeline. The asynchronous pipeline over which control is sought includes a data path and a control path. In accordance with the method of the present invention, a data tag value is assigned to the data prior to its entry into the asynchronous pipeline. The data tag value is sent into the control path at the same time the data is sent into its data path such that the data tag value passes through the asynchronous pipeline in parallel with the data to which it is assigned. At a given stage within the asynchronous pipeline, the data tag value is compared with a control tag value, and only in response to the data tag value matching the control tag value is the data permitted to pass to the next stage within the asynchronous pipeline.

摘要： An interlocked pipelined CMOS (IPCMOS) family of logic circuits provides extremely high performance pipelined operation and guarantees error free operation where variations in timing are compensated for automatically by the circuits. The IPCMOS logic circuits also provide a standard interface that makes it possible to interface different macro types easily. The IPCMOS logic circuits feature interlocking in both the forward and reverse directions. This “handshaking” guarantees error free timing and makes it possible to eliminate the need for a global clock at the macro level. Timing signals are generated locally at the macro level from the handshaking signals between macros. This makes it possible for the local circuits to deal with global timing variations caused by power supply noise, ACLV, and parameter variations. The macros operate in a pipelined mode with data advancing automatically from macro to macro with the timing controlled by the local handshaking signals. This pipelined operation results in an extremely fast cycle time. Another feature of IPCMOS is that the data inputs to a macro are only sampled when the data is in a valid state. making the concept of a standard macro interface possible. With this standard interface, different logic types such as static and dynamic circuits can be easily interconnected and the concept of reusable macros becomes a reality.

摘要： A comparator circuit for comparing two voltage levels in a C-2C A/D and D/A converter, comprising four cross-coupled active devices (FETs) in a latch arrangement whereby an offset voltage is used to compensate for imbalances in the comparator. The comparator includes a first FET having its gate electrode connected to the output of the D/A converter, and a second FET having its gate electrode connected to an analog input voltage. The first and second FETs each have one of their electrodes connected to a common voltage source. A third and a fourth FET have one of their electrodes connected respectively to the other electrode of the first and second FETs at first and second common nodes, respectively. The output of the comparator is provided at one of such first and second common nodes. The first and second nodes are also respectively connected to the gate electrodes of the fourth and third FETs in a cross-coupled arrangement. The other electrode of both the third and fourth FETs are connected to a common phase voltage source. An offset voltage is generated at the input to either of the gate electrodes of the first and second FETs to set the comparator at a balance point and thereby compensate for the differences in the threshold voltages and current carrying capabilities of the four FETs. Also, the comparator has relatively high input impedance, gain and bandwidth.

摘要： Leakage current control devices include a circuit having one or more functions in a data path where the functions are executed in a sequence. Each of the functions has power reduction logic to energize each respective function. A leakage control circuit interacts with the power reduction logic, so that the functions are energized or deenergized in a control sequence such that the functions where the data is resident are energized and at least one of the other functions is not energized.

摘要： A device for tensioning web, such as a plastics web dispensed from a shuttle in a wrapping machine, is disclosed. The wrapping machine usually includes an endless track positioned about an object to be wrapped and the shuttle travels on the endless track, dispensing the web as it goes. The rate at which web is dispensed varies as the shuttle progresses around the track and is dependent upon the shape of the track and the shape of the object to be wrapped. The web tensioning device attempts to maintain a constant tension in the web and includes a pair of rollers covered with resilient material. The rollers are urged together to form a nip with the resilient covering of the rollers compressed in the nip. The web is fed between the nip of the rollers.
