HyperPhysics is an exploration environment for concepts in physics which employs concept maps and other linking strategies to facilitate smooth navigation. For the most part, it is laid out in small segments or “cards”, true to its original development in HyperCard. The entire environment is interconnected with thousands of links, reminiscent of a neural network..
Students should go thru this website from cover-to-cover, It is a work of knowledge that is priceless
“Ampere’s Law states that for any closed loop path, the sum of the length elements times the magnetic field in the direction of the length element is equal to the permeability times the electric current enclosed in the loop.”
The Inventory of a Firm should be Open within an Organization. Searching with a browser, Integrateable with departmental webware/intranet. With a very easy readable non-programmer friendly API.
The Search must be based on Multiple Keywords, Filters or Tags. Dormant Inventory and Parts/Equipment/Furniture not on any live project anymore, Excess Inventory and Obsoleted Parts due to Tech Advancement; should be flagged. This enables other departments to use it, consume it for Maintenance or Research projects or integrate into new designs if not-obsolete.
If found to be valueless, damaged or worn-out by all departments and responsible engineers, then inventory should be sold or given away. The Employees can be the first customers for an inhouse Corporate Garage Sale. An un-organized, complexly-computerized and non-transparent/blocked Stores will end up in a Flea Market.
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.
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.
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.
