An operational amplifier is described which uses separate loops to control the output voltage and the error voltage between its inputs. To a large extent this architecture combines the high-speed characteristics of “current feedback” amplifiers with the low input referred errors of precision architectures. The technique has been applied to produce an amplifier with precision characteristics comparable...
This investigation presents a Domestic Indirect Feedback Compensation (DIFC) operational amplifier for systems with both low voltage and high voltage circuits. The DIFC operational amplifier is capable of converting a voltage signal from a low voltage circuit and amplifying it into a large voltage signal to drive high voltage load. Since the Metal-Insulator-Metal (MIM) capacitors are not designed...
