Bootstrap sweep circuit
In miller sweep circuit the polarity of sweep voltage is negative. In bootstrap sweep circuit the polarity of sweep voltage is positive.
The inverting amplifier is used in this circuit. The non inverting amplifier is used in this circuit.
The open circuit gain of the amplifier is A = – ∞ The open circuit gain of the amplifier is A = + 1
The linearity of the sweep voltage is better than that of the bootstrap sweep circuit. The linearity of the sweep voltage is poor than that of the miller sweep circuit.
A voltage source V is simulated like that V is always equal to the instantaneous capacitor voltage VC. A voltage source V is suggested like that V is forever equal to the immediate capacitor voltage VC.
