    Abstract: An integrated circuit includes a functional core configured to execute functional logic instructions; a functional memory device coupled to the functional core; a safety core configured to execute safety check logic instructions; a monitored address memory device coupled to the functional core and the safety core, the monitored address memory device configured to store memory addresses to be monitored; and a first safety memory device coupled to the functional memory device and the safety core. When a value in one of the monitored memory addresses changes, the changed value of the one of the monitored memory addresses is stored in the functional memory device and in the first safety memory device. The safety core performs a safety check on the changed value of the one of the monitored memory addresses stored in the first safety memory device.

    Abstract: An electrostatic discharge circuit includes two or more GGNMOS transistors where each transistor includes two types of body contact regions. Body contact regions of one type are non substrate isolated from body contact regions of the other type. A body contact region of one type is electrically coupled to the source region of its transistor and a body contact region of the other type is electrically connected to at least one other body contact region of the same type of another GGNMOS transistor.

    Abstract: A two-stage test process for testing IC packages having integrated launchers includes a first stage in which an RF-accurate test process is used to perform RF-accurate tests on a sample set of IC packages to obtain RF-accurate test results and a loop-back test process is performed to obtain loop-back test results. Test characterization data is obtained by comparing the RF-accurate test results to the loop-back test results. In a second stage, larger-scale testing is performed solely with the loop-back test process, and the loop-back test results for each tested IC package are compared with the test characterization data to characterize the test operation of the tested IC package. The loop-back test process can employ a test jig employing a PCB-mounted or PCB-integrated loop-back structure for relatively rapid test setup and test processing.

    Abstract: A fault detection system includes a state register, an error detection code (EDC) register, logic circuitry, an EDC generator, and an EDC checker. The state and EDC registers store first reference data and first checksum data, respectively. The logic circuitry executes a logic function based on the first reference data to iteratively generate second reference data that is different from the first reference data, and updates the first reference data of the state register with the second reference data of one iteration. The EDC generator iteratively generates second checksum data based on the iteratively generated second reference data and updates the first checksum data of the EDC register with the second checksum data of one iteration. The EDC checker detects a fault in the IC based on the updated first reference data and the updated first checksum data.

    Abstract: An amplifier circuit comprising: a first-stage residue-reduction storage unit; a final-stage residue-reduction storage unit; and a switching network. The switching network is operable to control the amplifier circuit according to the following operational configurations: a first residue-reduction configuration; a second residue-reduction configuration; and an operational configuration. Such an amplifier circuit uses a low number of residue-reduction steps to reduce global residual voltage to a very low level when the amplifier circuit is subsequently used in the operational configuration.
