Abstract:
An apparatus and method is described herein for reducing noise in a power distribution network for an interface. The power distribution network is characterized. And based on that characterization, worst case patterns for the interface are predicted and avoided. As one example, characterization includes providing a stimulus, such as a step function stimulus, and determining a mathematical function response, such as a step function response. Then, based on the step function response, a resonant frequency for the power distribution network is determined; from which patterns that cause the resonant frequency are identified/predicted. And when identified patterns are detected, they are scrambled or manipulated to avoid causing a worst-case noise scenario in an interface's power distribution network.
Abstract:
A Dynamically Terminated Bus (DTB) comprising a transmission line coupled to a plurality of dynamically configurable components and a bus protocol that only permits a single component to transmit at a time. Each of the dynamically configurable components can be configured as a single unbalanced complementary metal-oxide-semiconductor (CMOS) pull-up driver and a gunning transceiver logic (GTL) on-die, pull-up termination receiver. However, only one dynamically configurable component can be configured as the CMOS pull-up driver at a time. Embodiments of the present invention provide a high speed, DTB for coupling to the components.

Technologies for monitoring contact between one or more electrodes of a biofeedback monitoring device and a user include an electrode contact analysis device. The electrode contact analysis device is configured to transmit a body coupled communication (BCC) reference signal via a transmission electrode and receive biofeedback signals received by an electrode of the biofeedback monitoring device. The electrode contact analysis device is configured to process the received biofeedback signals to produce a received BCC reference signal from the received biofeedback signals and determine a quality of a contact between the electrode and the user based on the received BCC reference signal.

The high reference output and the low reference output are coupled to the ground plane and the power supply plane, respectively. The high reference voltage generator and the low reference generator are capable of communicating the high reference voltage signal and the low reference voltage signal to the receiver.
Abstract:
A variable delay path circuit having delay paths of different lengths is disclosed. Any of the delay paths can be selected to match the operating conditions of the system. In one embodiment of the invention, a delay path circuit having two delay paths connects a driver and receiver. Each of the two delay paths contains sites at both ends for placing zero ohm resistors, solder or copper slugs. To select one of the two delay paths, zero ohm resistors, solder or copper slugs are placed in the sites at the ends of the desired delay path. The delay is then dictated by the time it takes for a clocking signal to travel the length of selected delay path.
