Answers can be found at www.pearsonhighered.com/floyd. 1. The JFET is (a) a unipolar device (b) a voltage-controlled device (c) a current-controlled device (d) answers (a) and (c) (e) answers (a) and (b) 2. The channel of a JFET is between the (a) gate and drain (b) drain and source (c) gate and source (d) input and output 3. A JFET always operates with (a) the gate-to-source pn junction reverse-biased (b) the gate-to-source pn junction forward-biased (c) the drain connected to ground (d) the gate connected to the source 4. For VGs = 0 V, the drain current becomes constant when Vps exceeds (a) cutoff (b) VDD (c) Vp (d) 0 V 5. The constant-current region of a FET lies between (a) cutoff and saturation (b) cutoff and pinch-off (c) 0 and Ipss (d) pinch-off and breakdown 6. Ipss is (a) the drain current with the source shorted (b) the drain current at cutoff (c) the maximum possible drain current (d) the midpoint drain current 7. Drain current in the constant-current region increases when…

4. (d) the eedba Calculate the oscillator frequency. Determine the necessary value of R₂ in Figure 16-57 so that the circuit will oscillate. Neglect the forward resistance of the zener diodes. (Hint: The total gain of the circuit must be 3 when the zener diodes are conducting.) Explain the purpose of R3 in Figure 16-57.
