Abstract

Заявляемая группа изобретений относится к электронике и радиотехнике, а именно к электронным усилителям, в частности к усилителям звуковой частоты Hi-Fi, Hi End. Для усилителя и ЦАП достигается получение любого масштабного коэффициента преобразования и сдвига; устранение эффекта Миллера; устранение фазового сдвига; устранение динамических искажений; устранение общих обратных связей; устранение интермодуляционных искажений. Для повторителя достигается повышение КПД до около 50%; устранение фазового сдвига; устранение динамических искажений; устранение интермодуляционных искажений; подавление четных гармоник сигнала; симметричность действия повторителя во всем диапазоне напряжений входного сигнала; обеспечение защиты от короткого замыкания на нагрузке. Усилитель содержит входной импульсный трансформатор, выход которого соединен со входом описанного далее ЦАП, выход которого соединен с описанным далее повторителем напряжения. При этом напряжения питания связаны между собой одним из соотношений V>V≥V>V≥Vили V<V≤V<V≤V. ЦАП содержит предварительный конвертер, выполненный с возможностью преобразования цифрового кода на входе в ток на выходе, питание которого осуществляется от вводов питания постоянного тока с напряжениями Vи V. При этом выход предварительного конвертера соединен со входом повторителя тока, выход которого является аналоговым выходом ЦАП и через нагрузочное сопротивление соединен с вводом питания постоянным током с напряжением V. При этом общий вывод повторителя тока соединен с вводом питания постоянным током с напряжением V. Повторитель напряжения содержит последовательную цепь первого управляемого источника тока The claimed group of inventions relates to electronics and radio engineering, namely to electronic amplifiers, in particular to audio amplifiers Hi-Fi, Hi End. For an amplifier and a DAC, any scaling and shear coefficient is obtained; elimination of the Miller effect; phase shift elimination; elimination of dynamic distortions; elimination of common feedbacks; elimination of intermodulation distortion. For a repeater, an efficiency increase of up to about 50% is achieved; phase shift elimination; elimination of dynamic distortions; elimination of intermodulation distortion; suppression of even signal harmonics; the symmetry of the action of the repeater in the entire voltage range of the input signal; protection against short circuit on the load. The amplifier contains an input pulse transformer, the output of which is connected to the input of the following DAC, the output of which is connected to the voltage follower described below. In this case, the supply voltages are interconnected by one of the ratios V> V≥V> V≥V or V <V≤V <V≤V. The DAC contains a pre-converter, configured to convert a digital code at the input to the output current, which is powered from DC power inputs with voltages V and V. The output of the pre-converter is connected to the input of the current repeater, the output of which is the analog output of the DAC and the load resistance is connected to the input power supply with a constant current with voltage V. In this case, the common output of the current repeater is connected to the input power supply with a direct current with voltage V. Repeater voltage contains a serial circuit of the first controlled current source
