Abstract:
Methods of extending runtime with battery ripple cancellation in a CPU based system by providing a CPU that includes an input pin capable of throttling the power consumed by the CPU responsive to the input of a throttling signal, sensing a ripple in the form of a decrease in voltage or an increase in current responsive to a load on a CPU power supply, and when the ripple exceeds a predetermined limit, providing a throttling signal to the input pin to throttle the CPU to reduce the ripple.
