In my early learning/building days 80s/90s, Chips and Hybrids of Analog Devices and Burr Brown were very expensive and their performance was unquestionable. They made building sensitive and precision instruments easy for an Instrumentation design engineer.

Process Control & Industrial Automation – Analog Devices

Another brand that was good/expensive for analog was Datel-GE. Another GE company called Intersil made the best chip-solutions with cmos. They not only worked well, they were also affordable and had low power consumption.

“There is a long gap between engineering college and mid career in a non-engineering position, but technology marches on so a simple method of keeping abreast with the latest developments is required. This application note starts with an overview of the basic laws of physics, progresses through circuits 1 and 2, and explains op amp operation through the use of feedback principles.”

EE Books of 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. Designing Analog Chips by Hans Camenzind Hans Camenzind was born and raised in Switzerland and moved to the U.S. after college. He received an MSEE from Northeastern University and an MBA from the University of Santa Clara. After several years doing research in the Boston area, he moved to the West Coast to [Read More ....]

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 TIADCs and [Read More ....]

Precision RMS Value of AC Waveform

“RMS to DC conversion is the truest way to measure the energy contained in an AC waveform.” The accurate measurement of AC for a wide variety of waveforms and noise is difficult. When we make solar systems and inverters, the AC outputs are seldom sinusoidal. The easy method is to use a Precision rectifier/filter, get the average voltage and a RMS calibration/scaling is done for sine is by tweaking a trimpot. This will not show the right values for other waveforms. The other way was, analog computing, with many opamps and a matched pair of transistors; like multipliers and log [Read More ....]

“Careful study of CMOS characteristics show that CMOS devices used in a system design can be used for linear building blocks as well as digital blocks. Utilization of these new devices will decrease package count and reduce supply requirements. The circuit designer now can do both digital and linear designs with the same type of device.” CMOS Linear Applications AN-88 Application Note July 1973 74-CMOS Inverter Biased for Linear Mode Operation, Some Oscillators, Square wave and One Shot using MM74C04.

MAX1169 ADC and PIC Microcontroller

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 [Read More ....]
