ABSTRACT:
A row driver circuit receives a supply voltage and operates to develop a boosted voltage having a magnitude that is equal to the sum of an incremental boost voltage and a magnitude of the supply voltage. The magnitude of the incremental boost voltage is a function of the magnitude of the supply voltage to maintain the boosted voltage at an approximately constant value independent of variations in the supply voltage. A method of generating a boosted voltage includes detecting a value of a supply voltage, generating an incremental boost voltage having a value that is a function of the detected supply voltage, and adding the generated incremental boost voltage to the supply voltage to generate the boosted voltage.
