Question 7 of 7
Identify as many active loads as you can in the following schematic of an LM741 operational amplifier circuit,along with their respective (amplifying) transistors:
Reveal answer- Q6 is an active load for Q4
- Q23 is an active load for Q4
- Q13 is an active load for Q17 and Q22
Notes:Even if students do not yet know what an “operational amplifier” circuit is, they should still be able to identify transistor stages, configurations, and active loads.
