Or leave the gain = 1 and and another stage immediately after to provide the gain required. This way you get a nice clean signal and at the gain you need.
You beat me to it! He does show a better approach in the next video, but I think it would be interesting to compare your approach with the instrumentation amplifier.
i don't understand the original schematic based on KVL. based on the original schematic, v_1 = v_cm and v_2 = v_cm. and since v_cm is w.r.t. ground, there's a closed loop. so v_cm - v_cm + v_transducer = 0. this intutively doens't make sense
Thank you for making these! I've had some trouble understanding differential amplifiers for a while, but this clears things up! Keep up the good work.
Very helpful for review before my exam. Thank you.
Meaningful details analysis and systematic approach. Thanks.
