A card reader with power-saving function is used for being inserted with a memory card so that a computer can access the memory card through the card reader. When the memory card is inserted in the card reader, the card reader is enabled to operate. On the other hand, when the memory card is not inserted in the card reader, the card reader enters to a power-down mode for saving power.

Host device with power-saving function

Disclosed is an adjusting circuit for determining a target delay clock signal of a delay circuit having a plurality of delay units. The delay circuit generates a plurality of delay clock signals, and the adjusting circuit includes: a difference signal generating circuit, for generating a plurality of difference signals according to a reference clock signal and the delay clock signals; a delay processing circuit, coupled to the difference signal generating circuit, for determining the target delay clock signal by computing a corresponding number of delay units for a specific phase of the reference clock signal according to the difference signals; wherein the target delay clock signal is one of the delay clock signals.
