    • The invention relates to an electronic device which comprises a voltage regulator for providing a regulated output voltage to an electronic circuit and a control stage coupled to control the voltage regulator. The control stage is further configured to detect a request for a change of a system configuration of the electronic circuit coupled to receive the output voltage of the voltage regulator, to determine an activity factor of the electronic circuit for the requested system configuration, to determine a system clock frequency of a system clock of the electronic circuit, to determine a required current drive level of the voltage regulator based on the activity factor, the system clock frequency or the product of both, and to adjust the current drive level of the voltage regulator to the requested current drive level.
    • 本发明涉及一种电子设备,其包括用于向电子电路提供调节的输出电压的电压调节器和耦合以控制电压调节器的控制级。 控制级进一步被配置为检测耦合以接收电压调节器的输出电压的电子电路的系统配置的改变的请求,以确定所请求的系统配置的电子电路的活动因子,以确定 系统时钟频率的电子电路的系统时钟,基于活动因子,系统时钟频率或两者的乘积来确定电压调节器所需的电流驱动电平,并调整电压调节器的当前驱动电平 到所请求的当前驱动器级别。
