With his colleague Robert Boylestad at Queensborough College, they were the authors of many fundamental publications on electronic devices and circuits. Their seminal work "Electronic Devices and Circuit Theory" is a university level text that is currently in its 11th edition (April 30, 2012) and which was initially published in 1972.
A phase-shift oscillator is a linear electronic oscillator circuit that produces a sine wave output. It consists of an inverting amplifier element such as a transistor or op amp with its output fed back to its input through a phase-shift network consisting of resistors and capacitors in a ladder network.
Full hybrid-pi model. The full model introduces the virtual terminal, B′, so that the base spreading resistance, r bb, (the bulk resistance between the base contact and the active region of the base under the emitter) and r b′e (representing the base current required to make up for recombination of minority carriers in the base region) can be represented separately.
The semiconductor materials used in electronic devices are doped under precise conditions to control the concentration and regions of p- and n-type dopants. A single semiconductor device crystal can have many p- and n-type regions; the p–n junctions between these regions are responsible for the useful electronic behavior.
After sharp criticism from anesthesiologists, an insurance company is halting its plan to limit the amount time it would cover anesthesia used in surgeries and procedures. Anthem Blue Cross Blue ...
A mix of high-profile and local races will take place in the first few months of this year, which could serve as a barometer for how voters feel just months after the 2024 presidential election.
In electronics, biasing is the setting of DC (direct current) operating conditions (current and voltage) of an electronic component that processes time-varying signals. Many electronic devices, such as diodes , transistors and vacuum tubes , whose function is processing time-varying ( AC ) signals, also require a steady (DC) current or voltage ...
