Trillium erectum is a perennial, herbaceous, flowering plant that persists by means of an underground rhizome.

This is an example of Electromagnetism. Even Electromagnetic Relays and Power Contacters work on the same principle. Relays and Contacters.
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 Nevertheless, they contain some material that is hopelessly outdated.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.
ViPEC is a powerful tool for the analysis of high frequency, linear electrical networks. It takes a schematic description of the electrical network and performs a linear analysis in the frequency domain.
The output is in the form of port parameters (S, Y or Z) with results presented on a user defined grid, Smithchart or table. It can also be used to compute other characteristics like stability factors and group delay.
