2587a83389 Cross-coupled switched capacitor[edit]. Dickson charge pump[edit]. Illustration of the described operation, with Us = 100V . A tripler is a popular type of voltage multiplier. An ideal 4-stage Dickson multiplier (5 multiplier) with an input of 1.5 V would have an output of 7.5 V. A voltage multiplier may be formed of a cascade of voltage doublers of the cross-coupled switched capacitor type. Villard cascade voltage multiplier. For this reason, in the popular CMOS technology ICs the transistor which forms the basic building block of circuits is the MOSFET.
Assuming that this is the same level as the DC input voltage then an n stage multiplier will (ideally) output nVin. The most common type of voltage multiplier is the half-wave series multiplier, also called the Villard cascade (but actually invented by Heinrich Greinacher). On the next clock cycle ϕ 1 {displaystyle phi {1} } again goes low and now ϕ 2 {displaystyle phi {2} } goes high pushing the top plate of C2 to 3Vin. The output voltage of a tripler is in practice below three times the peak input voltage due to their high impedance, caused in part by the fact that as each capacitor in the chain supplies power to the next, it partially discharges, losing voltage doing so. Another difficulty is that there are parasitic capacitances to ground at each node. Each component only needs to be concerned with the relative voltage differences directly across its own terminals and of the components immediately adjacent to it. The circuit works by alternately switching the output of each stage between a voltage doubler driven by ϕ 1 {displaystyle phi {1} } and one driven by ϕ 2 {displaystyle phi {2} } .
