摘要： An integrated circuit (IC) including at least one combinational logic path. The combinational logic path includes two types of logic blocks cells that compensate each other for fabrication parameter effects on cell transistors. The two types may be dense cells with field effect transistor (FET) gates on contacted pitch and isolated cells with FET gates on wider than contacted pitch. Dense cell delay changes from the FET gates being printed out of focus are offset by isolated cell delay changes.

摘要： A temperature independent reference circuit includes first and second bipolar transistors with commonly coupled bases. First and second resistors are coupled in series between the emitter of the second bipolar transistor and ground. The first and second resistors have first and second resistance values, R1 and R2, and third and second temperature coefficients, TC3 and TC2, respectively. The resistance values being such that a temperature coefficient of a difference between the base-emitter voltages of the first and second bipolar transistors, TC1, is substantially equal to TC2×(R2/(R1+R2))+TC3×(R1/(R1+R2)), resulting in a reference current flowing through each of the first and second bipolar transistors that is substantially constant over temperature. A third resistor coupled between a node and the collector of the second bipolar transistor has a value such that a reference voltage generated at the node is substantially constant over temperature.

摘要： A circuit to discharge a capacitance between input terminals of a power system is disclosed. An example circuit includes a control circuit coupled to an input of a power system. The control circuit is coupled to detect whether an electrical energy source is coupled to an input of the power system. A switch is also included and is coupled to the control circuit and to the input of the power system. The control circuit is coupled to drive the switch in a first operating mode when the electrical energy source is coupled to the input of the power system. The control circuit is coupled to drive the switch in a second operating mode when the electrical energy source is uncoupled from the input of the power system. A capacitance coupled between input terminals of the input of the power system is discharged through the switch to a threshold voltage in less than a maximum period of time from when the electrical power source is uncoupled from the input terminals of the power system.

摘要： A circuit generates control signals used in pulse width modulation. A square wave signal generator generates a square wave signal based on the value of a sawtooth signal. The sawtooth signal has a maximum voltage level and a minimum voltage level. The voltage level of the sawtooth signal is compared with a first voltage slightly above the minimum voltage level. When voltage of the sawtooth signal is increasing and reaches the first voltage, a rising edge of the square wave is generated. The voltage level of the sawtooth signal is also compared with a second voltage slightly below the maximum voltage level. When voltage of the sawtooth signal is increasing and reaches the second voltage, a falling edge of the square wave signal is generated.

摘要： In an example embodiment, a method of automatically generating data validation rules from data stored in a column of a table is provided. Outliers for the data are determined by analyzing a profiling statistic for the data, the profiling statistic having a type. Then it is determined if a predefined limit is exceeded, based on a quantity of the outliers determined for the data through the analysis of the profiling statistic. A data validation rule is then automatically generated based on non-outliers detected in the data through the analysis of the profiling statistic, the generated data validation rule also being based on the type of the profiling statistic. The data validation rule can then be applied to data subsequently entered for the column, causing at least a portion of the data subsequently entered for the column to be rejected.
