A very simple but highly efficient combination lock circuit is shown in the figure. Any type of on/off switches can be used, varying from commercially available inexpensive types to more ...
The circuit in the figure shows a low-cost solution based on a transistor switch (Q1). The transistor is off under normal conditions, when the differential amplifier built around U1 amplifies the ...
It’s not as though you create complex transistor circuits in the way your 1960s equivalent would have done, but it’s still pretty fundamental to working with electronics even in 2018.
But with our simple transistor circuit, 20 mA will always flow. Well. Sort of. A Matter of Compliance Practical current sources have a certain range of compliance because they can’t provide an ...
However, as is sometimes the case, you can replace a complicated circuit by a simple one without much loss of performance. For example, transistors and resistors replace the entire IC . The circuit ...

The team designed a paper-based amplifier-type circuit that incorporated resistors, capacitors and a transistor. They first used wax to print channels onto a sheet of paper in a simple pattern. After ...
As with many inventions, two people had the idea for an integrated circuit at almost the same time. Transistors had become commonplace in everything from radios to phones to computers, and now ...
