Design Exploration Tools Encourage More Creativity Product News 11/30/2004 Post a comment What if a design tool had the hooks and means to capture a design, but, also had an inherent functionality to encourage you to creatively iterate, or explore? Instead of doing design iterations to fix problems, iterations would be done to streamline the design.
IP Flourishes But Designer Beware Product News 11/30/2004 Post a comment There is a growing number of companies who's product is IP. They capture their expertise in a descriptive language wrapper, and sell it. It is the logical step in the evolution of functional complexity.
Timing Integration Spawns Sequel Part Product News 11/30/2004 Post a comment Modern designs have tighter and more stringent timing constraints in place and there is very little margin for error when it comes to wander, jitter, skew and slew, and rise/fall times. With more attention paid to clocking and clock distribution, central control can be more effective once a built system has been characterized.

Signal conditioning compensates for bridge sensor errors News & Analysis 11/24/2004 Post a comment Offset and span are the fundamental parameters that describe how bridge sensors function, writes this TI amplifier guru in the November Planet Analog magazine. Offset is the output of the sensor without any applied stimulus. For an ideal bridge all the resistance elements would be exactly matched and the offset would be zero, he say. In reality, the offset can be a significant percentage of the sensors full scale output (FSO). A typical offset of 15 percent is common for many sensor types. Here'
IR-linked sensor simplifies temperature monitoring News & Analysis 11/24/2004 Post a comment It's difficult to obtain the temperature of a circuit component whose potential is several tens of volts from ground, and the job becomes harder as that voltage increases, write Maxim's applications team. Temperature measurements in high-EMI environments are also difficult, they say. A good solution for such cases is to implement a temperature probe linked to the readout location only by an infrared (IR) signal. The provision of power for the sensor can be simplified by minimizing power consumpt

As data rates begin to move beyond 25 Gbps channels, new problems arise. Getting to 50 Gbps channels might not be possible with the traditional NRZ (2-level) signaling. PAM4 lets data rates double with only a small increase in channel bandwidth by sending two bits per symbol. But, it brings new measurement and analysis problems. Signal integrity sage Ransom Stephens will explain how PAM4 differs from NRZ and what to expect in design, measurement, and signal analysis.
