Western Electric revives U.S. vacuum tube manufacturing at AXPONA 2026, showcasing 300B and 308B amps and plans for new 12AX7 ...

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 ...

In today’s information-driven society, there’s an ever-increasing preference to measure phenomena such as temperature, pressure, light, force, voltage and current. These measurements can be used in a ...

The common source amplifier is one of three basic single-stage amplifier topologies. The MOS version functions as an inverting voltage amplifier. The gate terminal of the transistor serves as the ...

Operational amplifiers (op amps) may initially look intimidating, but with a bit of study, they can be easily understood and used in a variety of applications. Op amps can be thought of as a perfect ...
