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 1):
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 provide the first voltage at a first node, including:\n a power node configured to receive a third voltage; \n a first slew rate driver configured to receive an input signal; \n a second slew rate driver coupled to the first slew rate driver at the first node, and configured to receive the input signal and further configured receive a fourth voltage that is less than the third voltage, \n a bias transistor between the power node and the first slew rate driver, wherein the bias transistor is configured to provide a current to the first slew rate driver, \n wherein the bias transistor is configured to control the current responsive to the second voltage, \n wherein the first slew rate driver is configured to provide the third voltage to the first node responsive to the input signal at a first logic level, and \n wherein the second slew rate driver is configured to provide the fourth voltage to the first node responsive to the input signal at a second logic level different from the first logic level.
