Abstract
The present disclosure provides designs and techniques to improve turn 'off' times of a bootstrapped switch, maximizing the total 'on' time of the bootstrapped switch. The techniques described herein provide a protection device coupled to the bootstrapped switch. The protection device may be controlled by an input voltage to the bootstrapped switch during a boosting phase and may be controlled by a constant voltage during a non-boosting phase. The techniques for reducing turn “off” times are particularly useful in high-speed applications, such as high-speed, low-voltage analog-to-digital converters.
