WebFigure 13. Balanced slew rate follower waveforms. An alternate approach to improving the emitter follower is to reduce the effective r e through negative feedback. Reducing r e can be addressed by adding a second transistor to increase the negative feedback factor by increasing the open-loop gain. The single transistor is replaced by a pair with 100% … 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. don lighthouse st catharines
