ThermalTrak integrates power output transistors with thermal bias diode. One of the major design concerns in the output section of a typical class AB audio amplifier is output bias and stability over ...

RF power amplifiers with LDMOS and GaAs transistors can provide excellent performance but require temperature-compensated bias circuitry. This article discusses how a programmable, linear ...

Back gating, body bias, substrate bias, and back bias all refer to a technique for dynamically adjusting the threshold voltage of a CMOS transistor. CMOS transistors are often thought of as ...

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 ...

Last time on Circuit VR, we looked at creating a very simple common emitter amplifier, but we didn’t talk about how to select the capacitor values, or much about why we wanted them. We are going to ...

There are times when you need to bias a low-current load and simply didn’t want to add another voltage regulator, or where you need a reasonable level of voltage accuracy, so a simple voltage divider ...
