Abstract
The described embodiments of the present invention provide a voltage generation circuit for biasing a particular node to a selected voltage level. A circuit is included for monitoring when the voltage supply to the integrated circuit is well above optimal specifications. When this circuit detects an over-voltage condition, a signal is provided to multiplexing circuitry which causes a higher frequency input signal to be provided to a voltage generating charge pump. Thus, the charge pump capacity is increased. In other embodiments of the present invention other factors may be sensed and the appropriate signal supplied to the charge pump driving circuitry to provide higher biasing levels. For example, current may be sensed at the voltage supply inputs to determine when the circuit is drawing a high level of current.
