Abstract: Examples of improved charge pumps are disclosed. In one example, a system comprises a first charge path comprising a first stage to boost an input voltage and a second stage to boost a voltage received from the first stage of the first charge path; and a second charge path comprising a first stage to boost an input voltage and a second stage to boost a voltage received from the first stage of the second charge path; wherein an output of the second stage of the first charge path is coupled to the first stage of the second charge path and an output of the second stage of the second charge path is coupled to the first stage of the first charge path.
