According to an exemplary implementation, a voltage regulator includes an emulated ripple generator. The emulated ripple generator includes a high side switch configured to control charging of an emulated ripple. The emulated ripple generator further includes a low side switch configured to control discharging of the emulated ripple. The high side switch and the low side switch are configured to control the charging and the discharging such that the emulated ripple is substantially in-phase with an inductor current of the voltage regulator. The high side switch can be configured to control the charging by selectively enabling a high side current source. Furthermore, the low side switch can be configured to control the discharging by selectively enabling a low side current source.
