Claims (2)

1. Способ повышения быстродействия операционного усилителя с непосредственной связью каскадов, содержащего нелинейный входной дифференциальный каскад с ограничением выходного тока, выход которого связан с буферным усилителем и корректирующим конденсатором, заключающийся в формировании с помощью дополнительного дифференциального каскада тока заряда (разряда) корректирующего конденсатора, отличающийся тем, что дополнительный ток заряда (разряда) корректирующего конденсатора формируют пропорционально разности между текущим значением напряжения на корректирующем конденсаторе и мгновенным выходным напряжением вспомогательного дифференциального каскада, включенного параллельно нелинейному входному дифференциальному каскаду с ограничением выходного тока.1. A method of increasing the speed of an operational amplifier with a direct connection of cascades containing a nonlinear input differential cascade with a limitation of the output current, the output of which is connected to a buffer amplifier and a correction capacitor, which consists in the formation of a correction capacitor using an additional differential cascade, characterized in that the additional charge (discharge) current of the correction capacitor is formed in proportion to the difference between the current value voltage at the correction capacitor and the instantaneous output voltage of the auxiliary differential cascade connected in parallel with the nonlinear input differential cascade with limitation of the output current. 2. Способ по п.1, отличающийся тем, что текущее значение напряжения на корректирующем конденсаторе определяют путем измерения выходного напряжения буферного усилителя, коэффициент передачи по напряжению которого выбирают близким к единице.2. The method according to claim 1, characterized in that the current voltage value on the correction capacitor is determined by measuring the output voltage of the buffer amplifier, the voltage transfer coefficient of which is chosen close to unity.
