All the circuits we worked with in the previous ... circuit Take a moment to consider the most basic common base amplifier. The transistor’s base is held at a constant bias potential, its ...

Immediately, I learned that the common base configuration gain was ... Started building my first hobby circuits at age 11 using the venerable 1N34A diode & 2N107 transistor. In high school, I knew ...

When Enable is high, a low-going SCL signal drives the emitter of one of the transistors as a common-base amplifier. The 10-kΩ resistor ... References 1 and 2 treat similar level-translation circuits.

The base resistor is thus usually of a high value, typically in the several hundred kiloohm range. In the days of germanium transistors you would even see circuits without a bias resistor that ...
