Abstract
A self-adjusting apparatus including a clock generator built within an IC generates an adjusted internal oscillating clock signal by referring to an external target signal while the IC is running in a normal mode, and a method for adjusting the internal oscillating clock signal of an IC by using the apparatus. While an IC is operating in a normal mode, which is a more power-consuming mode, the apparatus adjusts the internal oscillating clock signal of the IC by referring to the frequency of an external clock signal generated by an external clock generator. When the IC is forced to run in a power-down mode, which consumes less power, the self-adjusting apparatus is still able to provide a precise internal oscillating clock signal required for operating the electronic circuit without the presence of an external clock signal.
