Amps Week 8

Gain Bandwidth Product, Reason for Negative feedback for frequency response, Schmitt Trigger, Rin / Rout. Major lab for unit with 555 window comparator

The average op amp has very low open loop bandwidth. At a barefoot 200,000 X gain, the average op amp only has a bandwidth of about 10 Hz.
Using negative feedback with our op amp increases the bandwidth but costs us some gain.
