Abstract: Embodiments of a jitter detection circuit are disclosed that may allow for detecting both cycle and phase jitter in a clock distribution network. The jitter detection circuit may include a phase selector, a data generator, a delay chain, a logic circuit, and clocked storage elements.

Abstract: A dynamic level shifter circuit and a ring oscillator implemented using the same are disclosed. A dynamic level shifter may include a pull-down circuit and a pull-up circuit. The pull-up circuit may include an extra transistor configured to reduce the current through that circuit when the pull-down circuit is activated. A ring oscillator may be implemented using instances of the dynamic level shifter along with instances of a static level shifter. The ring oscillator may also include a pulse generator configured to initiate oscillation. The ring oscillator implemented with dynamic level shifters may be used in conjunction with another ring oscillator implemented using only static level shifters to compare relative performance levels of the static and dynamic level shifters.

Abstract: A level shifting multiplexer is disclosed. In one embodiment, a multiplexer is coupled to receive a first input signal from circuitry in a first power domain and a second input signal from circuitry in a second power domain. The multiplexer is configured to output a selected one of the first and second input signals to circuitry in the second power domain. The multiplexer also includes a level shifter circuit. When the first input signal is selected, the level shifter circuit may be enabled. When enabled, the level shifter circuit may level shift the first signal such that its voltage swing corresponds to that of the second voltage domain. The multiplexer may also include isolation circuitry configured to inhibit the level shifter.

Abstract: In an embodiment, an aging analysis tool may be configured to identify transistors that are expected to experience aging effects according to worst case stress vectors and/or designer identified worst case conditions. The aging analysis tool may modify a representation of the circuit (e.g. a netlist), replacing the identified transistors with aged transistors (e.g. by modifying parameters of the transistors in the netlist). The aging analysis tool may process the modified netlist over a range of conditions at which the circuit is expected to operate, to ensure that the design meets specifications after aging. The process may be repeated until the aged design meets specifications (with circuit modifications made by the designer to improve the design).

Abstract: A saboted projectile comprises a sub-caliber, spin-stabilized warhead (usually an armor-piercing penetrator) and a full caliber spin-stabilized non-disintegrating sabot capable of being fired by airplanes. The sabot releasably receives the armor-piercing penetrator and is adapted to be mounted on a conventional ammunition cartridge. The sabot includes a novel method of holding the penetrator until firing, tightening a reverse threaded end cap against the aft end of the penetrator during firing and utilizing interior end cap geometry to utilize firing gas pressure to accelerate the penetrator forward in relation to the sabot after leaving the gun barrel. Accuracy is increased by maintaining axial symmetry and releasing the penetrator in substantially the same way each time. There are other novel features.
