Question

Three of these devices form a negative feedback loop in the Wilson current mirror. Two of these devices are biased with the same current in modern differential, or “long-tailed,” pairs. These devices can exhibit a small-signal output resistance (20[1])due to the Early effect, (20[2])which is represented (20[1])by adding a resistor to the hybrid-pi model. A type of these devices transitions from (*) triode mode to saturation (10[2])mode (10[1])when the voltage between the gate (10[1])and the drain exceeds a threshold. (10[3])These devices (10[1])come (10[1])in “bipolar (10[1])junction” (10[3])and “field-effect” (10[3])types. (10[4])The number of these devices in an IC doubles every year according to Moore’s (10[1])law. (10[5])For 10 (10[1])points, (10[1])name these semiconductor devices that act as three-terminal switches or amplifiers. ■END■ (10[3])
