Analog Circuits and Mixed Circuits Design

Electronic Design provides leading-edge technical information to electronics engineers and engineering managers around the world; individuals responsible for the design and development of electronic original equipment manufacturers’ products and systems.

Electronic Design – Magazine

Electronic Design keeps its readers abreast of rapid technological advances and their applications at the chip, board and systems levels.

“Once upon a time I couldn’t even spell “Web Freak”, and now I am one. But several people agreed, that in response to the popular demand, RAP should put out a “Web Page” with several kinds of useful information on it.”

What is the use of a Robot, which cannot perceive its environment in detail. Where can a Control system be effective, if it does not get a “feedback” about its actions. How could one do Analysis and Research or Verify, when he cannot Measure a parameter with good accuracy and resolution.

ADC are the Eyes and Ears for a uC, this brings the Real world as Numbers within the CPU. Without ADC a uC is like a Frog in the Well and has to create an Imaginary World for himself. That is beyond the scope of Engineering.

Bring your favorite PIC Microcontroller to his senses. Give him an ability to Perceive the Reality around him. Get him an Analog to Digital Converter and don’t forget to code.

MAX1169 ADC and PIC Microcontroller

MAX1169 ADC is better than 4 1/2 Digit Value. For me the Intersil chip is a Benchmark. Beyond 5 1/2 Resolution may be needed only for Scientific Research.

I would add, 2 1/2 is like Analog Meters/Bar Graphs, 3 1/2 for Control systems, 4 1/2 for T&M and beyond 5 1/2 is for R&D.  – delabs Notes

Interfacing the MAX1169 ADC to a PIC Microcontroller – Maxim

Abstract: This application note describes how to interface a MAX1169 analog-to-digital converter (ADC) to a PIC microcontroller. It includes an example circuit and software for a PIC18F442. The software contains function calls to interface the ADC to the PIC microcontroller using the internal MSSP I²C port at 400kHz.

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.

Intersil’s products include amplifiers, analog front ends, communication interfaces, data converters, digital potentiometers, display solutions, DSL solutions, optical storage products, power management products, real time clocks, switches/MUX’s, etc. In 2017 Intersil  became a part of Renesas.

Intersil - Analog and Power Semiconductors

Intersil – Analog and Power Semiconductors

Intersil has developed into a leading analog semiconductor manufacturer with five specialized product groups: Consumer Power, Consumer Electronics, Analog Mixed Signal, Industrial Communications and Automotive & Military/Space Specialties.

History

Intersil was founded in 1967. After being acquired by General Electric Corp in 1981, it was sold to Harris Corporation in 1988, at which point the name was retired. Intersil at Wikipedia.
