Abstract: Disclosed herein are a frequency generator, which is provided with a frequency automatic correction function and is capable of reducing a frequency test time and a correction time, and a method of correcting a frequency thereof. The frequency generator includes an oscillator configured to generate an output frequency signal according to a frequency control signal, and a frequency corrector configured to generate the frequency control signal for controlling the output frequency of the oscillator using a reference frequency signal.

Abstract: Disclosed are a system and a battery management integration circuit using an incremental analog-to-digital converter (ADC), which can reduce the consumption of the amount of a bias current. The system includes an incremental ADC configured to perform accumulation on an analog signal during an oversampling period and a bias current generator configured to provide a bias current for the accumulation of the incremental ADC. The bias current generator provides a first amount of the bias current in a first period defined from start timing of oversampling to preset timing during the oversampling period, and provides a second amount of the bias current, smaller than the first amount of the bias current, in a second period subsequent to the first period.
