Audio Amplifier with Bootstrap connection - Electrical ...
https://electronics.stackexchange.com/questions/364955/audio-amplifier-with-bootstrap-connection
The arrangement where AC-coupled feedback from a voltage follower is taken back into a bias arrangement to raise its effective impedance is called bootstrapping, and is also often found raising the impedance of input bias resistors …
Bootstrap Amplifier Circuit using Transistors
https://circuitdigest.com/electronic-circuits/bootstrap-amplifier-circuit-using-transistors
In Bootstrap amplifier, bootstrapping is used to increase the input impedance. Due to which the loading effect on the input source also decreases. The design looks similar to the Darlington pair, having a bootstrap capacitor. Bootstrap capacitor is used to provide AC signal’s positive feedback to the base of the transistor.

Improving Transimpedance Amplifiers with a Bootstrap
https://www.analogictips.com/improving-transimpedance-amplifiers-bootstrap/
Improving transimpedance amplifiers with a bootstrap April 26, 2021 By Chris Francis Analog bootstrap circuits are traditionally ones where output is fed back to the input, usually to increase input impedance. This can be to minimize either the resistive or reactive (usually capacitive) components of the input impedance or both.
Bootstrapping your op amp yields wide voltage swings - …

A variety of monolithic op amps is available, and each features fully factory-specified performance that you can apply even when a bootstrapping network surrounds the op amp. Extending the voltage range of standard op amps by bootstrapping offers you flexibility and maintains a “canned” set of performance parameters.
