 Battjes had designed a 300 MHz transistor amplifier at [[Sylvania]] before he joined Tektronix in 1961 to work on high-speed amplifiers.
-He invented the [[ft doubler|"f<sub>t</sub> doubler" amplifier topology]] that has a current gain of 2 even at the transit frequency of the transistors that are used in the circuit.

 In 1971, Battjes left the portable oscilloscope group and joined the IC design group within Tektronix.

 So I arrived at this premier oscilloscope company feeling somewhat of a fraud.

 <blockquote>
-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.
