Question
1. _____ Class A 2. _____ MOSFET 3. _____ Class C 4. _____ JFET 5. _____ Self-Bias 6. _____ Common-Source A. Analogous to the common-emitter BIT. B. The most common type of JFET bias. C. Analogous to the common-collector BJT. D. When fidelity requirements override efficiency. E. Forward-biased in normal quiescent operation. F. Operates with a reverse-biased pn junction to control current in a channel. Can be p channel or n channel. G. Reverse-biased in normal quiescent operation. H. Mas no pn junction and requires special ESD handling. I Eliminates crossover distortion. J. Usually used in RF applications, such as RF oscillators and modulators. The one advantage of a push-pull class AB amplifier is that it: A. reduces 'loading' effects. B. has a high current gain. C. has low input impedance. D. eliminates 'cross-over distortion'. The affect(s) the voltage gain at the high end of the bandwidth (frequency response) in an amplifier. A. AC input resistance B. internal capacitance C. external coupling capacitors D. AC output resistance The JFET produces maximum I_d when: A. V_gs = -5 V B. V_gs = -1 V C. V_gs = -3 V D. V_gs = 0 V Class A MOSFET Class C JFET Self-Bias Common-Source BE Junction Class AB CB Junction Common-DrainExplanation / Answer
