Web• In order for the BJT to sink (or source) large currents, the base current, iB, must be large. Providing large currents as the voltage gets to extreme values is difficult for MOSFET circuits to accomplish. • If one considers the MOSFET driver, the emitter can only pull to within vBE+VON of the power supply rails. This value can be 1V or more. 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… inappropriate elf on the shelf memeWebBJT. for short.
