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
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.
