Activity: The Emitter follower (BJT) [Analog Devices Wiki]

A voltage buffer amplifier is used to transfer a voltage from a first circuit, having a high output impedance level, to a second circuit with a low input impedance level. The interposed buffer amplifier prevents the second circuit from loading the first circuit unacceptably and interfering with its desired operation, since without the voltage buffer the voltage of the second circuit is influenced by output impedance of the first circuit (as it is larger than the input impedance of th… WebADALM2000 Activity: The Emitter Follower (BJT) by Doug Mercer and Antoniu Miclaus Download PDF.

Assuming the same BJT parameters and using a dc analysis as in Example 2, 1, we get VBE = 0.82 V and IE = 4.95 mA. Consequently, VC = 6.1 V, but this does not affect the small-signal amplifier parameters (using the T model).

WebNov 30, 2011 · Voltage follower using BJT is also known as emitter follower. +Vcc is the transistor’s collector voltage, Vin is the input voltage, Vout is the output voltage and Re is the transistors emitter resistor. Voltage follower implemented using opamp is shown in Fig 2. In electronics, a common collector amplifier (also known as an emitter follower) is one of three basic single-stage bipolar junction transistor (BJT) amplifier topologies, typically used as a voltage buffer. In this circuit the base terminal of the transistor serves as the input, the emitter is the output, and the collector is common to both (for example, it may be tied to ground …

WebMay 22, 2024 · The key characteristics of a voltage follower are a high input impedance, a low output impedance and a non-inverting voltage gain of approximately one.
