Abstract:
A voltage generator comprising;a voltage source that provides an output voltage in dependence upon a feedback signal, a scaler, operably coupled to the voltage source, that scales the output voltage to form a scaled output voltage, a comparator, operably coupled to the scaler, that provides the feedback signal in dependence upon a comparison between the scaled output voltage and a programmed reference voltage, and a divider network, operably coupled to a fixed reference voltage and to the comparator, that provides the programmed reference voltage having a maximum value that is less than the fixed reference voltage, wherein the maximum value of the programmed reference voltage is based on component values of one or more components within the divider network, the one or more components within the divider network include: a first capacitor, operably coupled to the reference voltage, and a programmed capacitor, operably coupled to the first capacitor and to the programmed reference voltage, and the maximum value is dependent upon a ratio that includes the capacitance value of the first capacitor and a capacitance value of the programmed capacitor.
