The '''f<sub>t</sub> doubler circuit''' is a transistor amplifier topology, invented by [[Carl Battjes]], | |||
that has a current gain of 2 even at the transit frequency of the transistors that are used in the circuit. | |||
* [http://w140.com/US3633120.pdf US Patent | It is used heavily in Tektronix instruments and several Tektronix integrated circuits implement this approach. | ||
