It was also around this time that I was asked to take over the instructor responsibilities of “AFTR”, Amplifier Frequency and Transient Response, an in-house course developed by Carl Battjes. I wasn’t sure I was up to the challenge, but soon became comfortable in this new role. AFTR was a virtual pre-requisite among analog designers. Carl’s focus had been solely on vertical amplifiers, so I added a lot of new material related to the design of other types of amplifiers. I ended up teaching the course for 7 years. Some years later when Carl became terminally ill, he begged me to “write the book” for him. Alas, I did not have the time, having moved on into a very different design realm. | It was also around this time that I was asked to take over the instructor responsibilities of “AFTR”, | ||
