WebThe emitter-follower amplifier is also known as a common collector amplifier. It is a single-stage bipolar junction transistor, or BJT, often used as a voltage buffer. This is because it can be used for high input and low output impedance. It can help match impedance in circuits. WebDarlington Transistor pairs can be made from two individually connected bipolar transistors or a one single device commercially made in a single package with the …

If the emitter voltage is about 6V then when it swings -2.8V to 3.2V, R2 will sink only 320mV. So the returning current causes the emitter voltage to rise, turning off Q1 and creating a flat spot at the bottom of the waveform. ttrpg background music
