In this lesson, students build two circuits and explore how transistors function. When Bell Labs introduced the transistor in June of 1948, a spokesman proudly announced "This cylindrical object . . .

Scientists are facing a number of barriers as they try to develop circuits that are microscopic in size, including how to reliably control the current that flows through a circuit that is the width of ...

In order to test and characterize optical front end circuits, a controllable, high bandwidth, microamp-level current source is needed. However, most optocouplers on the market have large CTR variation ...

Explains the principles of transistor switching circuits, highlighting their role in electronic computers. It contrasts transistors with vacuum tubes, emphasizing that transistors function as ...

An electric current is a flow of charged particles. A source of energy, such as a cell or battery, is required to make the free electrons move in one direction. Electrons are negatively charged ...

If you think about an asylum, there are two kinds of people in it: staff and patients. We aren’t sure which one [Nick Lucid] is in the latest The Science Asylum video that tries to answer the question ...

Inductance is the link between electric circuits and magnetic fields. Voltage and current sine waves are in-phase when they peak and cross the zero axis at the same time. However, this rarely happens ...

ROHM Semiconductor today announced the development of the TLR1901GXZ, an ultra-compact CMOS operational amplifier (op amp) that achieves the industry’s lowest operating circuit current. Optimized for ...

ORNL researchers are designing and increasing the capacity of a new type of semiconductor-based circuit breaker, which can operate faster as compared to mechanical switches.

Have you ever wondered what makes a loudspeaker “difficult to drive”? Do you wonder what’s so special about an amplifier that is stable into a 4 ohm load? If these are the kinds of questions that ...

ROHM’s ultra-compact CMOS Operational Amplifier (op amp) TLR1901GXZ achieves the industry’s lowest operating circuit current.
