Designing Mixed Analog Chips and Circuits

These are some updates on Analog and Mixed Design pages online. A/D Converters are important because the world is full of mainly analog signals and parameters. Processing, Filtering, Analyzing and Computing data is best done by software (firmware).

These days the term of firmware can only be used for very small devices. This is because we have more memory, flash and computation ability in tiny footprints. So even a mini gadget can have a Tiny OS sometimes even a Virtual Machine. What is a VM it is is a OS in a OS. Java, .Net.

Time-interleaved Analog-to-digital Converters

Time-interleaved Analog-to-digital Converters

TIADCs and TI-ADCs an Article by Dr. Christian Vogel.
"The idea of a time-interleaved ADC (TIADC) is to use a system of M parallel channels, which alternately take one sample (time-interleaved sampling). Thereby, the sampling frequency of one channel does not need to fulfill the Nyquist criterion; however, when in the digital domain all samples are merged into one output sequence the overall sampling frequency fulfills the Nyquist criterion"

The Designer's Guide Community - A Guide to Simulation & Modeling for Analog & RF Circuit Designers

A Site where analog, mixed-signal and RF circuit designers come to learn about simulation, modeling and design. There are a number of very practical papers on simulation and modeling on the Analysis, Modeling, and Theory pages. A collection of useful example models can be found on the Verilog-AMS page.

Designing Analog Chips by Hans Camenzind

Hans Camenzind book on Analog CMOS design is a good reference for students and covers Power Electronic concepts like Switching Regulators and Low Drop-Out Regulators. The Delta-Sigma Converter A/D and Zero-Crossing Detectors on Mixed Design. Communications circuits like Timers and Oscillators . Phase-Locked Loops and Filters too.

Web Studio is a powerful HMI SCADA software

Using a browser from any Thin Client PC or Tablet view Status, Annunciations, Alarms and monitor online history data. Visualize data for Analysis or Tuning. Monitor real time process parameters to optimize the plant production.

Now plants have to be energy conscious and keep in mind the environment health, like air and water. Most important is a consistent yield of a job which is within stated quality and reliability. Worker/Plant safety is also a part of process quality and cost effectiveness..

Web Studio is a powerful HMI/SCADA software

Web Studio - SCADA Open HMI Software

Some Nice Features

Security: Multi-levels of application security. Easily restrict application access.

Reports: Create and E-mail concise reports in RTF, XML, PDF, CSV, and HTML file formats (via remote connection). Store reports internally, or automatically download to a remote location via new FTP configuration interface.

Scalable: Reduce development costs by easily scaling projects from one interface/operating environment to another.

Industrial control and Networking – Freescale

Wired and wireless industrial communications protocols and human machine interface. Motorola Semiconductors became Freescale. You may recall that some rugged Mosfets, Bridges and Drivers were developed by Motorola Semiconductor. The Factory Automation have the resources reference to integrate this expertise of high-reliability electronics into your process control systems.

Industrial control and Networking - Freescale

Battery-operated mobile robots

Battery-operated mobile robots, to high-performance processors that control leading factory robots and vision systems. Control and motion in service robots for dangerous, strenuous or repetitive tasks (handling warehouse inventory, assisting nurses, security,construction, mining, industrial cleaning, waste handling, firefighting, rescue.

delabs Notes

In product development, the most important thing is to communicate and interact with the customer. To get the inputs very clear, goes a long way in customer satisfaction and project's technical success.
Even if the customer is not able to create a Black Box Specifications but is able to indicate the need or problem. Then you can arrive at the specs by incremental prototyping, to gather full requirements.
