    摘要: A system, method and computer program product for implementing a quiescent current leakage specific model into semiconductor device design and circuit design flows. The leakage model covers all device geometries with wide temperature and voltage ranges and, without the need for stacking factor calculations nor spread sheet based IDDQ calculations. The leakage model for IDDQ calculation incorporates further parasitic and proximity effects. The leakage model implements leakage calculations at different levels of testing, e.g., from a single device to a full chip design, and are integrated within one single model. The leakage model implements leakage calculations at different levels of testing with the leverage of a single switch setting. The implementation is via a hardware definition language code or object oriented code that can be compiled and operated using a netlist of interest, e.g., for conducting a performance analysis.

    摘要: The invention discloses a process for preparing a polynuclear ferric hydroxide-saccharide complex, including: adding an aqueous solution of an alkaline substance drop-wise into an aqueous solution of iron salt at a temperature of 5-20° C. until pH 6-8, collecting the polynuclear ferric hydroxide from the reaction mixture by a conventional method; reacting the polynuclear ferric hydroxide with a saccharide in a solution of an alkaline substance for 10-40 hours at 106-125° C. under pH 10-12, resulting in a crude product having an isoelectric point of 4.4-5.3 and a weight average molecular weight of 20,000-100,000 Daltons, and then harvesting the polynuclear ferric hydroxide-saccharide complex from the crude product. The process can precisely control the molecular weight of the polynuclear ferric hydroxide-saccharide complex without an effect on the other characteristics of the product, for example its saccharide content or isoelectric point etc. Furthermore, it is very simple and readily applicable in industry.

    摘要: A data frame switching apparatus has number data ports and a port traffic management unit for each port. Each port traffic management unit includes a physical layer unit for receiving and transmitting data frames, a serial shift register for temporarily storing a portion of each received data frame in serial data format, and a port controller for extracting each data frame's source and destination address from the portion of the data frame stored in the serial shift register. A crossbar switch connects any specified one of the data ports that is receiving a data frame to another one of the data ports so as to transmit the received data frame to a corresponding destination. A global traffic manager and lookup engine map the destination address of each received data frame to a corresponding destination port, determine the availability of the destination port, and when the destination port if available, send setup signals to the switch so as to connect the data port on which the data frame is being received to the destination port.

    摘要: A clock and data recovery circuit has an input port for receiving a data signal representing a sequence of data values, a pulse generator, a clock generator and a data storage element. The pulse generator generates a pulse whenever a data value change is detected in the received data signal. The clock generator generates a clock signal having an associated frequency and phase. The clock generator receives each pulse produced by the pulse generator so as to synchronize the clock signal's phase with data value changes on the input port. The data storage element stores data values in the data signal at times dictated by the generated clock signal. The data values stored by the data storage element is the recovered data signal and the generated clock signal is the recovered clock signal. The pulse generator and clock signal generator interoperate so as to bound jitter in the recovered clock signal caused by any jitter in the received data signal so that the data values in the received data signal are stored during a data capture time window whose phase position is automatically compensated for the any jitter in the received data signal.
