A Wide-Band Feedback Amplifier based on A New Operational Current Amplifier in 130nm CMOS
International Conference on Electron Devices and Solid-State Circuits, 2019Two main topologies of feedback amplifiers are analyzed in detail in this paper. One is based on operational transconductance amplifier, but is limited in bandwidth. The other one is based on operational current amplifier, and can achieve wide bandwidth.

Current-feedback amplifiers versus voltage operational amplifiers
IEEE Transactions on Circuits and Systems I: Fundamental Theory and Applications, 2001This paper compares the main performance parameters of the current feedback opamp (CFOA) with those of a conventional voltage opamp (VOA). To make the comparison effective, a folded cascode VOA is considered (which is characterized by similar features and topology) and the same power consumption was assumed for both amplifiers.

A 0.1–52-GHz Triple Cascode Amplifier With Resistive Feedback
IEEE Microwave and Wireless Components Letters, 2019In this letter, a 0.1–52-GHz amplifier is designed and fabricated using a 0.15- $\mu \text{m}~{E}$ -mode GaAs pseudomorphic high electron-mobility transistor (pHEMT) process.

An approach to the problem of the design of transistor wide-band feedback amplifiers is given. Choice of feedback circuit configurations for the stabilization of amplifier circuit transconductance, transresistance, voltage gain, and current gain are discussed in terms of an idealized phase-reversing amplifier.

Stabilized Feedback Amplifiers*
Bell System Technical Journal, 1934This paper describes and explains the theory of the feedback principle and then demonstrates how stability of amplification and reduction of modulation products, as well as certain other advantages, follow when stabilized feedback is applied to an amplifier. The underlying principle of design by means of which singing is avoided is next set forth.

Feedback amplifier configurations
IEE Proceedings - Circuits, Devices and Systems, 2000Systematic relations exist between the four basic single-loop feedback amplifier configurations (voltage-gain, current-gain, transfer-admittance and transfer-impedance) and certain newer configurations for which bandwidth is independent of gain. Loop gain provides the link.

To explain that feedback can be applied to an amplifier in four ways. To distinguish between parallel and series feedback. To quantify the effect that feedback has on amplifier input and output impedances. To show that large amounts of applied negative feedback cause the amplifier to behave as one of the four basic types of amplifier.
