Bootstrap Circuit Using Transistor. The below figure shows the circuit diagram of the bootstrap sweep circuit. It typically involves the use of a bootstrap capacitor which provides positive feedback of ac signals to the base junction of a transistor in an emitter follower circuit.

Some all pmos integrated circuits such as the intel 4004 and the intel 8008 use that 2 transistor bootstrap load circuit. Application of this feedback increases the effective value of the base resistance. So vin is often accompanied by an equivalent thevenin resistance of significance.
Can anyone explain how to use the concept of bootstrap with transistor in order to raise the output.
If we are using a transistor we can able to amplify the signal by using the supply voltage. I e vin 5 volt and supply volt 12 volt in a transistor we can able to get a output of 12 volt. The below figure shows the circuit diagram of the bootstrap sweep circuit. The transistor q1 acts as a switch in this circuit and transistor q2 is fitted to act as an emitter follower.
