Abstract:

Various apparatuses, methods and systems for protecting a driver from electrostatic discharge are disclosed herein. For example, some exemplary embodiments provide a driver, including a buffer, a leakage path blocking transistor connected to an output of the buffer, and an output driver connected to an output of the leakage path blocking transistor. Current from the output driver to the buffer is substantially blocked by the leakage path blocking transistor.

International Classification:

H03F 3/26

US Classification:

330267, 330277

Abstract:

An amplifier is provided that includes an output portion that sources and sinks current associated with an output load and an amplification portion that is biased by a relatively small bias current with respect to an output current of the amplifier. The amplification portion provides an amplified output signal to the output portion. The amplifier further comprises at least one impedance component coupled between the output portion and the amplification portion to alter at least one pole associated with the amplifier to mitigate instability of the amplifier related to the relatively small bias current.

International Classification:

G06F 17/18
G06F 19/00

US Classification:

702179

Abstract:

Systems and methods are provided for performing an estimation using an iteratively reweighted least squares technique on a scenario defined by a design matrix, a response variable vector, and a parameter to be estimated. A system and method can be configured to include a root data processor, where a least squares estimate is calculated by the root data processor during each of a plurality of processing iterations. A plurality of node data processors can also be configured to: update values of a weight matrix according to a current state of the least squares estimate, determine a first intermediate value based on the design matrix and the weight matrix, determine a second intermediate value based on the design and weight matrices and the response variable vector. The root data processor calculates an updated least squares estimate based on the intermediate values.

International Classification:

C25D005/02

US Classification:

205/123000, 205/183000

Abstract:

A process for applying a metallization interconnect structure to a semiconductor workpiece having a barrier layer deposited on a surface thereof is set forth. The process includes the forming of an ultra-thin metal seed layer on the barrier layer. The ultra-thin seed layer having a thickness of less than or equal to about 500 Angstroms. The ultra-thin seed layer is then enhanced by depositing additional metal thereon to provide an enhanced seed layer. The enhanced seed layer has a thickness at all points on sidewalls of substantially all recessed features distributed within the workpiece that is equal to or greater than about 10% of the nominal seed layer thickness over an exteriorly disposed surface of the workpiece.
