A semiconductor device has an amplifier and common mode suppression (CMS) circuit formed on a common substrate. The CMS circuit has a first input and second input coupled for receiving an input signal and further has a first output coupled to a first input of the amplifier and a second output coupled to a second input of the amplifier to reduce common mode. The CMS circuit further has a ground plane, a first conductive trace disposed over the ground plane and coupled between the first input and first output, second conductive trace disposed over the ground plane and coupled between the second input and second output, and third conductive trace disposed over the ground plane with a first end of the third conductive trace coupled to the ground plane and a second end of the third conductive trace open circuit to form a resonator.

Circuit and method of providing common mode suppression for amplifier

A distributed amplifier system comprising an impedance matching network configured to match an input impedance to an output impedance of the signal source, and a DC block configured to block DC components in the input signal. A variable gain amplifier adjusts the gain applied to the input signal based on a gain control signal to generate a gain adjusted signal. An emitter follower circuit receives and processes the gain adjusted signal to introduce gain peaking to create a modified signal. A distributed amplifier receives and amplifies the modified signal from the emitter follower circuit, to create an amplified signal. The distributed amplifier includes a termination network and one or more impedance matching elements configured for gain shaping the amplified signal. The gain peaking introduced by the emitter follower circuit is controlled by a variable current source. The distributed amplifier may be an open collector distributed amplifier.

Systems and methods for transmitting a multimedia stream over a communication link on a network are disclosed. The systems and methods adaptively adjust encoding parameters based on monitoring changing conditions of the network. A transmitter includes an adaptive-rate encoder that adaptively adjusts a video encoding bit rate in response to changing conditions of the communication link. The encoder maintains tight rate control by utilizing slice processing and sub-frame rate adaptation, as well as maintaining a headroom between the channel bit rate and the video encoding bit rate. The adaptive-rate encoder also embeds intra-frame constraints in predictive frames traffic in order to reduce latency.

An assembly includes an electronic device having depressible controls and a navigation button which is positioned over the electronic device. The navigation button has a central portion, and directional lobes extending from the central portion. The navigation button initially resides in a non-pivoting orientation in which none of the depressible controls are actuated. The navigation button (i) pivots about a first axis in response to depression of a first directional lobe to actuate a first depressible control of the electronic device without actuating a second depressible control of the electronic device, and (ii) pivots about a second axis in response to depression of a second directional lobe to actuate the second depressible control of the electronic device without actuating the first depressible control of the electronic device. Each of the first axis and the second axis is offset from a midpoint of the navigation button.

An electronic system includes a chassis defining a substantially plane-shaped cavity. The chassis is arranged to contain an air stream (e.g., provided by a cooling subsystem) which flows from an air intake side of the chassis to an air exhaust side of the chassis through the substantially plane-shaped cavity. The air intake side of the chassis is opposite the air exhaust side of the chassis. The electronic system further includes a jacket circuit board disposed within the plane-shaped cavity, and a set of pluggable electronic modules. The jacket circuit board is oriented within the plane-shaped cavity to receive cooling from the air stream. Each pluggable electronic module is arranged to (i) electronically connect to the jacket circuit board through a front of the chassis and (ii) define a supplemental ventilation port through which air passes to augment the air stream.

A method and apparatus for processing interrupts in a computing system include processing for ordering a plurality of interrupts for at least one processor. Such interrupts include system event interrupts, external device interrupts, and may further include power management interrupts, interprocessor interrupts, and/or intraprocessor interrupts. Such processing continues by generating an interrupt enable/disable signal based on the current context of a corresponding processor such that when the processor is performing a particular task which should not be interrupted, an interrupt signal is prevented from being provided to the processor. The processing also includes generating masking information to provide enable/disable masking information regarding each of the plurality of interrupts. As such, the computing system may enable/disable on a per interrupt basis the processing of a given interrupt. Such selectability in the processing of interrupts on an individual basis or global basis may be processed dynamically thereby providing greater flexibility and efficiency in interrupt processing.

A grounding plug structure configured for push-type snap lock fastening in circuit board screw holes is provided with a resilient deformable conductive member. When a circuit board with one or more such plug structures fastened thereto is mounted with respect to a tray or chassis, the conductive portion of the plug structure is deformed against a surface of the tray, forming an effective conductive pathway, e.g., for grounding, between the tray and the circuit board. In this way, grounding pathways can be established while eliminating the need for at least some screw mounting and/or standoff structures.
