Disclosed are on-chip global electrical signaling systems and methods employing differential current-mode sensing having reduced delay and energy dissipation compared to conventional inverter repeaters. The present inventions can be used for point-to-point connections as well as N-to-1 connections.
摘要:
Disclosed is a memory architecture where current sense amplifiers are used instead of voltage sense amplifiers, and where the memory cells normally disposed along a single bit line are divided between two half bit lines. Each half bit line is coupled to a respective input of the current sense amplifier. When one of the memory cells is selected for reading, it couples a current related to its stored data state to the half bit line that it is coupled to. During this operation, a reference current is generated on the other half bit line. Also disclosed are novel current sense amplifiers.
摘要:
Disclosed are multiphase oscillators comprising a plurality of delay stages serially coupled in a loop by a plurality of nodes, with the loop being folded to provide two concentric rings of delay stages with equal numbers of allocated nodes. A second plurality of negative-resistance elements are provided, each element having a first output coupled to a node on the first concentric ring and a second output coupled to a node on the second concentric ring. Each such output switches between first and second voltage levels, and provides a negative resistance to a signal coupled to it during at least a portion of the transition between voltage levels. The outputs of an element switch to opposite voltage levels. With this construction, a high-voltage pulse propagates around the loop of delay stages, with a low-voltage pulse propagating behind it. Also disclosed are circuits to control the direction of pulse propagation.

Disclosed herein are embodiments of a speaker mounting assembly. In one such embodiment, the speaker mounting assembly comprises a speaker housing having a housing support surface, a speaker mounting bracket having a base surface, a projection extending from one of the speaker housing and the speaker mounting bracket and a mounting structure formed on the other of the speaker housing and the speaker mounting bracket. The mounting structure is configured to receive the projection such that the housing support surface contacts the base surface when the projection is received in the mounting structure. The mounting structure has an anti-rotation structure configured to prevent rotation of the speaker housing with respect to the speaker mounting bracket.

A method may include generating logical transition data for the logic cell based on an analysis of a digital model for the logic cell, the logical transition data including at least one entry indicative of an output transition of the logic cell occurring in response to an input transition of the logic cell. The method may also include generating a parameterized transition based analog model for the logic cell, the parameterized transition based analog model including transition timing parameters associated with each entry of the logical transition data. The method may further include generating an analog model for the logic cell based on the parameterized transition based analog model and one or more analog netlists characterizing the logic cell.

In some illustrative embodiments, an incoming signal from a transducer in an ultrasound imaging beam-former apparatus is applied to an in-phase sample-and-hold and a quadrature sample-and-hold. The quadrature sample-and-hold may be clocked a quarter period behind the in-phase sample-and-hold. The output of the sample-and-holds are applied to in-phase and quadrature analog-to-digital converters. A magnitude calculator receives the in-phase and quadrature digital values, and outputs a magnitude. A phase calculator receives the in-phase and quadrature digital values, and outputs a phase. An apodizer applies a difference between an amplitude of the outgoing signal and the magnitude and applies a first illumination to a image point in substantial proportion to the difference, and a phase rotator applies a second illumination to the image point in substantial proportion to the phase.

A treatment vessel for separating contaminants from a base liquid is provided. The vessel comprises a first cylindrical portion, a frusto-conical portion, a second cylindrical portion and a conical portion, the conical portion having a bottom outlet arranged to discharge heavy contaminants from the vessel. Over time, the heavy contaminants settle on the sides of the conical and frusto-conical portions. In order to remove the settled contaminants, the vessel is provided with at least one clarified liquid inlet disposed at or proximate to the frusto-conical portion. The clarified liquid is sourced from either the treatment vessel itself, or another treatment vessel in the same system. The clarified liquid is reintroduced into the vessel in a manner so as to cause a downward circular flow to scour out the frusto-conical portion and the conical portion so as to assist in removal of heavy contaminants that settle on the sides thereof.
