Типовая реализация инструментальных усилителей путем соединений трех операционных усилителей не позволяет получить высокую стабильность коэффициента усиления напряжения в широком диапазоне входного синфазного сигнала, особенно при большом усилении. Для решения указанной проблемы были изучены конструктивно-схемотехнические особенности прецизионных инструментальных усилителей фирмы Analog Devices и на основе результатов выполненного анализа разработаны основные блоки микросхем инструментальных усилителей с однополярным напряжением питания на биполярных транзисторах и полевых транзисторах, управляемых p-n-переходом. В статье для всех блоков приведены электрические принципиальные схемы и результаты схемотехнического моделирования, показывающие возможность программирования различного сочетания параметров.</p></abstract><trans-abstract xml:lang="en"><p>Instrumentation amplifiers, which are differential voltage amplifiers with high impedance at each input and a fixed gain, are widely used in various electronic equipment. The typical implementation of instrumentation amplifiers by connecting three operational amplifiers does not provide high voltage gain stability over a wide range of input common-mode signals, especially at high gain. To solve this problem, the design and circuitry features of precision instrumentation amplifiers from Analog Devices were studied. Based on the analysis results, the main blocks of instrumentation amplifier microcircuits with a single-supply voltage using bipolar transistors and junction field-effect transistors were developed. The article presents electrical schematic diagrams and circuit simulation results for all units, demonstrating the capability to program various combinations of parameters.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>прецизионный инструментальный усилитель</kwd><kwd>полевой транзистор</kwd><kwd>p-n-переход</kwd><kwd>однополярное напряжение питания</kwd></kwd-group><kwd-group xml:lang="en"><kwd>precision instrumentation amplifier</kwd><kwd>field-effect transistor</kwd><kwd>p-n junction</kwd><kwd>single-polarity supply voltage</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">Dvornikov O., Tchekhovski V., Popov A.
