For the following questions, tick ONLY all right answers, or fill in the blank. Non-linear devices (e.g. diodes, transistors) are generally used to control the flow of power in circuits. The conclusion from the BJT and MOSFET amplifiers that: Emitter follower (or source follower) can guarantee low loading effects at the input and output. Cascading various configurations of BJT (or MOSFET) amplifiers allow to improve the performance of amplifiers In a cascade amplifier, due to its low output Z, an emitter-follower circuit should be placed at the end to guarantee low loading effect at the output. In an electronic shop, one should select the amplifier with the: input impedance output impedance Highest In general, when comparing the BJT and MOSFET transistors, three main differences: The device is used widely in Digital circuits is The device that depends more on geometry (width, length, etc.) is The device that dissipates no power at the input (zero input current) is The general conclusion from the study of chapter 3, 4 and 5 is that, The analysis of non-linear electronic circuits like diode and BJT or MOSFET circuits is often accomplished in two steps; first, the dc analysis to determine the dc operating point which enables to determine a linear small-signal ac equivalent circuit for the non-linear device (e.g. diodes, transistors) in the circuit; second, the ac equivalent circuit is analyzed. The bandwidth of transistor-based amplifiers is determined mainly by the cutoff frequencies set by external (coupling and by-pass) capacitors and internal parasitic capacitors of transistors.
