ABSTRACT:
A circuit and method for generating a fractional multiple of a primary power supply voltage is disclosed. The circuit operates in two phases wherein during a first phase a first capacitor is charged to the primary power supply voltage Vdd, and during a second phase the voltage on the first capacitor is bootstrapped toward twice the power supply voltage. A second capacitor, however, is coupled in parallel to the first capacitor during the second phase to cause charge sharing. The circuit can thus generate a fractional voltage between Vdd and 2 Vdd without the need for any voltage regulator circuitry.
