Carl Battjes

Carl Robert Battjes (b. 30 December 1929 – d. 28 April 2007) was a Tektronix engineer.

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" 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.
