Abstract
Provided is a current control circuit. A current control circuit may include a clock sensing unit configured to generate a control signal according to one or more frequencies based on a plurality of clock signals, and a current scaling unit configured to scale a bias current according to the control signal. The current control circuit according to example embodiments may dynamically control a bias current according to one or more frequencies based on a plurality of clock signals so that power consumption of an analog-to-digital converter (ADC) and the semiconductor device including the ADC, which require various operating frequencies, may be improved.
