Abstract:
An apparatus and a method that provide a bias voltage to a charge pump circuit are described. An example apparatus includes: a bias voltage generator that receives a first voltage and provides a second voltage responsive to the first voltage; a charge pump circuit that receives an input signal and provides the first voltage. The charge pump circuit includes an inverter and a bias transistor. The inverter receives the input signal and provides a third voltage. The bias transistor coupled between a power node having a power supply voltage and a slew rate driver of the inverter. The bias transistor receives the second voltage and provides a power supply voltage to the slew rate driver responsive to the second voltage less than a threshold voltage and stops providing the power supply voltage to the slew rate driver responsive to the second voltage greater than the threshold voltage.

Claim (Index 9):
An apparatus comprising:\n a bias voltage generator configured to receive a first voltage and further configured to provide a second voltage responsive to the first voltage; and a charge pump circuit configured to receive an input signal and further configured to provide the first voltage, the charge pump circuit including:\n an inverter including a first slew rate driver and a second slew rate driver coupled to the first slew rate driver at a first node, the inverter configured to receive the input signal and further configured to provide a third voltage; and \n a bias transistor coupled between a power node having a first power supply voltage and the slew rate driver, \n wherein the bias transistor is configured to receive the second voltage and further configured to provide a current to the slew rate driver responsive to the second voltage, wherein the second slew rate driver is configured to receive a second power supply voltage that is less than the first power supply voltage, wherein the first slew rate driver is configured to provide the third voltage to the first node responsive to the input signal at the first logic level, wherein the third voltage is the first power supply voltage when the second voltage is less than a threshold voltage and wherein the third voltage is a third power supply voltage between the first power supply voltage and the second power supply voltage when the second voltage is greater than the threshold voltage, and wherein the second slew rate driver is configured to provide the second power supply voltage as the third voltage to the first node responsive to the input signal at the second logic level different from the first logic level.
