摘要： A circuit and method are given, to realize a high efficiency voltage multiplier for integrated circuits generating an internal and flexible positive or negative high voltage on-chip supply voltage from low external positive or negative supply voltages or ground. Applying multi-phase control signals to voltage boost internal nodes allows for eliminating threshold voltage drop losses and thus improves the voltage pumping gain compared to circuits with diode-configured FETs of prior art. Making use of voltage signals from antecedent stages in order to bias the bulk of MOS transistors fabricated in triple-well technology enables relaxing of the gate oxide stress within high order stage MOS transistors. Such a method, called leap-frog bulk potential tracking method, makes MOS transistors from different stages exhibit about the same body effect, which is very important because MOS transistors of higher order stages now show the same performance as MOS transistors from lower order stages. Important also in terms of efficiency as the charge sharing speed of high order MOS transistors always dominates the total charge pump performance and the driving force of pumped currents, thus also allowing for a greater number of serially connectable stages overall or a smaller number necessary for a certain targeted output voltage.

摘要： The present invention discloses a voltage conversion circuit having self-adaptive mechanism. A control branch includes a first resistor coupled between a second power supply and a control terminal, and a switch circuit that is coupled between the control terminal and a ground terminal and receives an input voltage from an input terminal to generate a control voltage at the control terminal. A voltage-withstanding P-type transistor circuit of an output branch is coupled between the second power supply and the output terminal that generates an output voltage and is controlled by the control voltage. A voltage-withstanding N-type transistor circuit of the output branch is coupled between the output terminal and the ground terminal and is controlled by an inverted input voltage. When the input voltage is at a first power domain high/low state, the output voltage is at a second power domain high/low state.
