В статье рассмотрены результаты экспериментальных исследований двухзатворного полевого транзистора с управляющим p-n-переходом, изготовленного по технологическому маршруту 3CBiT ОАО «Интеграл». На основе полученных результатов предложена электрическая модель двухзатворного полевого транзистора с управляющим p-n-переходом, описывающая особенности его применения в аналоговых интегральных микросхемах. Приведено сравнение результатов измерений и моделирования вольтамперных характеристик с использованием созданной модели при разных режимах управления затворами. Малая емкость и обратный ток верхнего затвора двухзатворного полевого транзистора с управляющим p-n-переходом, возможность компенсации постоянной составляющей входного тока обеспечивают значительное улучшение характеристик таких аналоговых интегральных микросхем, как электрометрические операционные усилители и зарядочувствительные усилители. Разработанный двухзатворный полевой транзистор с управляющим p-n-переходом может найти применение в устройствах считывания сигналов, необходимых в аналоговых интерфейсах датчиков космического приборостроения и ядерной электроники.</p></abstract><trans-abstract xml:lang="en"><p>One of directions of improving parameters of analog integrated circuits is a development of new and modernization of existing designs of integrated elements without significantly changing of a technological route of integrated circuit manufacturing with a simultaneous creation of new integrated elements models. The article considers the results of experimental studies of the double gate junction field-effect transistor manufactured according to the 3CBiT technological route of JSC Integral. Based on the obtained results, the electrical model of double gate junction field-effect transistor is proposed, which describes the features of its application in analog integrated circuits. Comparison of I-V characteristics of measurements results and created model simulation are presented. A small capacity and a reverse current of a double gate junction field-effect transistor top gate, an ability to compensate for the DC (direct current) component of an input current provide a significant improvement in the characteristics of analog integrated circuits such as electrometric operational amplifiers and charge-sensitive amplifiers. The developed double gate junction field-effect transistor can be used in signal readout devices required in the analog interfaces of space instrument sensors and nuclear electronics.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>полевой транзистор с управляющим p-n-переходом</kwd><kwd>двухзатворный транзистор</kwd><kwd>электрометрический усилитель</kwd><kwd>зарядочувствительный усилитель</kwd><kwd>компенсация входного тока</kwd></kwd-group><kwd-group xml:lang="en"><kwd>junction field-effect transistor</kwd><kwd>double gate transistor</kwd><kwd>electrometric amplifier</kwd><kwd>charge-sensitive amplifier</kwd><kwd>input current compensation</kwd></kwd-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Close J.P., Counts L.W.
