Packet 6: Tossup 10

Bob Wildar added emitter degeneration to a basic circuit named for this quantity, which he used three of in the 741 op amp’s design for biasing. A circuit named for this quantity, which uses only three transistors by incorporating a negative feedback loop, was developed over one night by George R. Wilson. Taking a differential pair and shorting the gate and drain together creates a “mirror” of this quantity, (15[1])which is ideally (15[2])zero at the (*) gate (-5[1])of a MOSFET. A ratio between two values of this quantity defines the BJT parameter beta. (10[1]-5[3])Any two-terminal (-5[1])linear circuit can be represented (10[1])as a resistor in parallel with a source of this (10[1])quantity (-5[2])by Norton’s theorem. (10[3]-5[1])This quantity (10[1]-5[1])squared (10[1])times R (10[3])gives the (10[1])power (10[1]-5[1])radiated (10[1]-5[3])by a resistor. (10[2]-5[1])For 10 points, (10[1])the “drain” value of what quantity (10[1])for a transistor might be 1 milliamp? ■END■ (10[9]0[2])
