On Actively Compensated Amplifiers Using Negative Impedance Converters

In this brief, we analyze two actively compensated amplifiers identified in a recently proposed negative impedance converter (NIC) regarding their phase and gain errors. We also study the use of this NIC in active compensation of a inverting amplifier and compare its performance with previously described actively compensated amplifiers. Further new NIC realizations using other actively compensated non-inverting amplifiers and their application to realize inverting amplifiers is also investigated.
