| 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. |
