Bipolar transistors used in a common emitter configuration to make a high frequency amplifier are sometimes defined for their small-signal properties under the assumption that the gain transistor's ...

What happens to voltage gain when a bipolar transistor is operated at low voltages (Vce < 1V). In a previous circuit that operated at a quiescent Vce of 0.75V, voltage gain was demonstrably low. This ...

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 ...

While attending APEC 2019, it seemed that gallium-nitride (GaN) transistors were just coming into their own in high-volume applications, while silicon-carbide (SiC) transistors have found wide ...
