Boosted sampling circuit and relative method of driving

摘要

A boosted sampling circuit that is relatively straightforward to form is provided, as well as a corresponding method for driving the same. The input voltage applied to the boosted sampling circuit may be equal to a supply voltage or may be greater than a maximum voltage level allowed by the prior art circuits. This result is attained by connecting the control nodes of a plurality of switches to the input node while a first control phase is active, and by connecting a current terminal of another switch to a biasing voltage for protecting it from breakdowns.
