Anticausal Analysis of Feedback Amplifiers
Bell System Technical Journal, 1977This paper discloses a technique for the direct analysis of linear active circuits, avoiding the solution of simultaneous equations. This is done by representing the circuit in such a way that the signal variables (currents and voltages) are determined sequentially: we only allow a signal variable to depend upon previously determined signal variables ...

To describe the basic properties of amplifiers without feedback. four types of amplifier model, the equivalence that exists between them, and which model to choose in practice. To quantify the effect of input and output impedance on amplifier performance, and to couple signal source, amplifiers and load to achieve good coupling of signal voltage ...

Transistorized Negative Feedback Amplifier
IETE Journal of Research, 1963ABSTRACTAn attempt has been made to present the broad approach to the design of a transistorized feedback amplifier with the help of conventional techniques. The design procedure is equally applicable to other type of single loop feedback amplifiers with suitable modifications.

Distortion in Feedback Amplifiers
1991Negative feedback applied to an amplifier linearizes the transfer characteristic of the amplifier and reduces the distortion of the input signal that is generated by the nonlinearity. The gain of the amplifier at an operating point is also reduced accordingly. These aspects are illustrated using the amplifier block diagram of Figure 5.1a.

Switched-gain feedback amplifiers
2015 IEEE 58th International Midwest Symposium on Circuits and Systems (MWSCAS), 2015We describe a simple switched-gain control technique for improving the settling time and peak overshoot of closed-loop amplifiers under power constraints. We consider the important particular case of two-pole amplifiers and show that the proposed compensation method out-performs standard linear compensation based on pole-splitting.

In Chapter 6 the application of feedback to amplifiers was found to be advantageous if it was in the form of simple negative feedback at medium frequencies. In this chapter, we shall investigate the circuits and connections necessary to produce this form of feedback for various amplifier configurations.

Differential-feedback magnetic amplifiers
Electrical Engineering, 1957In push-pull TYPE magnetic amplifiers with two single-ended external-feedback or self-saturating circuits in back-to-back connection, each of these circuits has its own positive-feedback component which reduces or nearly nullifies the intrinsic negative feedback of the ordinary saturable reactor (transductor).

L.F. Transistor Feedback Amplifier
IETE Journal of Research, 1963ABSTRACT1. If the feedback amplifier's circuit configuration allows its return ratio—Aβ to be expressed in factored form, the inherent poles and zeros contributing to its transmission characteristics are easily seen and could be employed for constructing a pole zero diagram.
