Feedback Amplifier Configurations

Feedback, Nonlinear, and Distributed Circuits, 2001
This chapter examines small-signal performance equations, general operating characteristics, and engineering design guidelines for the six most commonly used global feedback circuits. These observations derive from analyses based on the judicious application of signal flow theory to the small-signal model that results when the subject feedback network ...

Feedback Amplifier Theory

Feedback, Nonlinear, and Distributed Circuits, 2001
The use of negative feedback is fundamental to the design of reliable and reproducible analog electronic networks. This chapter examines the salient features of the theory that underlies the efficient analysis and design of commonly used feedback networks.

Feedback-amplifier design

Proceedings of the IEE - Part IV: Institution Monographs, 1952
The paper is concerned with the pole pattern required for a low-pass amplifier which is to have overall feedback. The analysis applies to an amplifier whose gain function contains no internal zeros and with a feedback fraction which is independent of frequency.

Current Feedback Instrumentation Amplifier With Built-In Differential Electrode Offset Cancellation Loop for ECG/EEG Sensing Frontend

IEEE Transactions on Instrumentation and Measurement, 2021
This work describes a compact and low-power current feedback instrumentation amplifier (CFIA) that can effectively eliminate differential electrode offset (DEO), amplifier input offset, and light motion artifacts.

A 1.7-dB Minimum NF, 22–32-GHz Low-Noise Feedback Amplifier With Multistage Noise Matching in 22-nm FD-SOI CMOS

IEEE Journal of Solid-State Circuits, 2020
A low-noise feedback amplifier (LNA) with interstage noise matching is implemented in 22-nm fully depleted silicon-on-insulator (SOI)-CMOS technology. Minimum noise figure (NF) is 1.7 dB centered at 28 GHz, and NF remains below 1.98±0.25 dB across a 10 ...

Feedback in Amplifiers

2021
The concept of feedback in amplifiers is equally important. Without feedback design, amplifier is worthless. So as to get better understanding of both types of feedbacks, positive and negative, the theory of feedback in amplifier is discussed in this chapter.

Implementation of a Charge-Sensitive Amplifier without a Feedback Resistor for Charge Detection Mass Spectrometry Reduces Noise and Enables Detection of Individual Ions Carrying a Single Charge.

Journal of the American Society for Mass Spectrometry, 2020
Charge detection mass spectrometry (CDMS) depends on the measurement of the charge induced on a cylinder by individual ions by means of a charge-sensitive amplifier.
