Custom IC layout, Schematic Capture, Languages such as VHDL and Verilog. An Open-source Electronic Design Automation, EDA. Electric VLSI uses connectivity for all design, even Integrated Circuit layout. This means that you place components (MOS transistors, contacts, etc.) and draw wires (metal-2, polysilicon, etc.) to connect them. The screen shows the true geometry, but it knows the connectivity too.
These are high-voltage, high-current Darlington transistor arrays. Each consists of seven NPN Darlington pairs that feature high-voltage outputs with common-cathode clamp diodes for switching inductive loads.
Many may already know about these EE Educational pages with Circuits of J. B. Calvert. These pages are valuable as they are like a summation of Important and Practical Sections in many EE Subjects. If you want to master the basics of EE, these pages will propel you in the right direction.

These old publications, from 1966 and 1963, respectively, are some of the finest works on op amp theory that I have ever seen. Nevertheless, they contain some material that is hopelessly outdated.
This includes everything from the state of the art of amplifier technology, to the parts referenced in the document - even to the symbol used for the op amp itself:
An Excellent way to expand your A/D convertors I/O capability. Multiple Analog Inputs can be routed to a single Opamp or Analog Input of a uC or uP System. Use protection Zeners or clamping inputs.
These devices consist of four independent voltage comparators that are designed to operate from a single power supply over a wide range of voltages. Operation from dual supplies also is possible, as long as the difference between the two supplies is 2 V to 36 V, and VCC is at least 1.5 V more positive than the input common-mode voltage.
An application from an old TI datasheet showing the versatility of this comparator. For me it was a workhorse and like LM324 was used in many products.
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.
OSHW Draft Definition 0.3 is based on the Open Source Definition for Open Source Software and draft OSHW definition 0.2, further incorporating ideas from the TAPR Open Hardware License. Open Source Hardware (OSHW) is a term for tangible artifacts - machines, devices, or other physical things - whose design has been released to the public in such a way that anyone can make, modify, distribute, and use those things.
