Abstract: A voltage regulation system provides a relatively stable voltage source without introducing the typical costs of a ground buffer. The disclosed voltage regulation system includes a voltage regulator that is operative to detect a change of the load current and regulate a current bypass mechanism to stabilize a total supply current. For example, the voltage regulator includes a current sensor and a current compensation circuit. The current sensor is configure to generate a current compensation signal based on the load current change, whereas the current compensation circuit is configured to adjust a bypass current in response to the current compensation signal. As a result, the bypass current dynamically compensates the load current change such that the ground voltage of a variable load becomes relatively stable over a range of load currents.
