DIGITAL RAMP RATE CONTROL FOR CHARGE PUMPS |
摘要 |
Methods for controlling a ramp rate of an output voltage derived from one or more charge pumps and reducing variation in the ramp rate due to process, voltage, and temperature (PVT) variations are described. In some embodiments, the ramp rate of the output voltage from one or more charge pumps may be controlled using a ramp rate control circuit that uses a digital counter to adjust (or step up) the output voltage from the one or more charge pumps based on a ramp rate schedule. The ramp rate schedule may specify varying output voltage levels for the one or more charge pumps during a time period in which the output voltage charges up from a first voltage to a second voltage greater than the first voltage. |
