A voltage boost system, IC and design structure are disclosed for boosting a supply voltage while preventing forward biasing of n-well structures. The voltage boost system may include a first voltage boost circuit producing a first boosted voltage using at least one voltage boost sub-circuit, each of the at least one voltage boost sub-circuit having an output passgate in an n-well; a second voltage boost circuit producing a second boosted voltage, the n-well of each output passgate being biased using the second boosted voltage, wherein the second boosted voltage is greater than the first boosted voltage. Voltage boost sub-circuits may use gate control circuitry to reduce gate oxide stress, thus allowing lower voltage level FETs to be used.
