Solid-state device technologies, which are available to the amplifier designer, fall, broadly, into three categories: bipolar junction transistors (BJTs) and junction diodes; junction field effect ...

Sometimes I wish FETs had become practical before bipolar transistors. A FET is a lot more like a tube and amplifies voltages. Bipolar transistors amplify current and that makes them a bit harder to ...

Insulated Gate Bipolar Transistors (IGBTs) have become pivotal components in modern power electronic systems, blending the high input impedance and fast switching capabilities of MOSFETs with the high ...

How do you sort through this overwhelming number of devices? One way is to start by selecting the optimal process technology. Most manufacturers clearly label an op amp as CMOS, bipolar, or even ...

It used to be a rite of passage to be able to do the math necessary to design various bipolar transistor amplifier configurations. This doesn’t come up as often as it used to, but it is still a good ...

Amplifiers are fundamental circuit-design elements. They drive everything from earbuds to antennas. Placed ahead of analog-to-digital converters (ADCs), they reshape signals from sources as diverse as ...

Members can download this article in PDF format. Use of differential signaling in analog front ends is increasing across a range of applications, from audio processing to factory automation.

The first transistor was successfully demonstrated at Bell Laboratories in Murray Hill, New Jersey, in 1947. This three-terminal device has spawned many of the electronics devices that make possible ...

Rotel just released the high performance RB-1582MKII (200-watt x 2) and RB-1552MKII (120-watt x 2) class A/B stereo power amplifiers. Each amplifier is built with an engineering philosophy called ...
