  • Fet-teld combination with capacitively coupled output electrode means
    Patent number: 4145624
    Abstract: A field effect transistor (FET) is connected in series to a transferred electron logic device (TELD), the TELD being a non-linear load resistor for the FET. The current thresholding property of the TELD and the saturation characteristics of the FET are utilized to produce an output pulsed signal of substantial voltage gain with fast rise time and short pulse width. An output electrode is capacitively coupled to the TELD to provide an output pulsed signal of alternating polarity for direct interconnection of devices in cascaded circuits.
