Description

This lecture covers the gain bandwidth product of a real operational amplifier, which decreases by approximately 20dB per decade beyond a certain cutoff frequency. The effect of feedback on the amplifier's bandwidth is explored through LTspice simulations, highlighting the importance of proper circuit assembly to avoid saturation. The presentation includes verification by LTspice, open-loop amplifier simulations, and the impact of feedback on the amplifier's frequency response. The instructor, Adil Koukab, demonstrates the consequences of incorrect assembly and the significance of feedback in amplifier design.
