I hope you keep uploading these videos. I love your textbooks, but many times you explain things more clearly in the videos, like how the capacitor in the bias input helps shunt the noise to ground. Your resources have helped me a ton!

I like to think that the combination of my videos and books is better than either one alone.

I've enjoyed and learned from your videos but with this one ... I've been struggling to understand how to properly power an inverting opamp. I got two points from this video that just got a very long tail end of a development project across the line! Thank you.

Can you please explain how the critical frequency of 1Hz for the noise affects the circuit??What is the significance of 1hz critical frequency as lower frequrncy limit for noise? For AC noise will the capacitor be short circuited at all frequency above 1Hz,thus grounding all the AC noises above 1Hz?

There's nothing magic or special about 1 Hz. The choice of critical frequencies will depend on the application. In general, yes, you can look at those capacitors as shorts for higher frequencies. That is an idealization, of course. The reactance of real-world caps do not follow the Xc formula as frequency increases to infinity. Secondary effects come into play.

Thanks for explain. I have a question; 7:26 Why do we see bias voltage 15V at Vout? When the non-inverting input is 15V, the gain is approximately Av = 5 due to the output (1+Rf/Ri) and we should see saturation (30V)? What am I doing wrong? thank you.

The DC gain is not 5. It's actually 1. You're forgetting the reactance of Cin (that's infinity in series with Ri at DC). If you remove Cin in the sim, you'll see that the output does indeed go to saturation.

It's TINA-TI, the free version of TINA, available from Texas Instruments (ti.com).
