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.

The bootstrap circuit is a very simple and low-cost solution for high-side MOSFET control on class-D audio amplifiers. Overdischarging on the bootstrap capacitors can occur in very extreme test cases. Using lower-frequency PWM settings (for example, 400 kHz) or a larger bootstrap capacitor (for example, 0.47 µF) can avoid this issue.

Unlike a true current source, the current through the bootstrap circuit will change with the supply voltage. This is a gradual change, and is outside the audio spectrum - or at least it should be if the circuit is designed correctly. Figure 6A - Active And Bootstrapped Current Source. The bootstrap circuit works as follows.
