Abstract: A flyback converter controller is provided with a single terminal through which the flyback converter controller senses for over-voltage faults for an input voltage and also senses for open circuit faults for an auxiliary winding. A first voltage divider provides a divided version of the input voltage to the single terminal. The controller compares a voltage for the single terminal to at least one over-voltage threshold to detect the over-voltage fault for the input voltage.

Abstract: The present disclosure relates to a signal acquisition device, a signal acquisition method and a wearable apparatus. A preamplifier circuit in the signal acquisition device amplifies an obtained sEMG signal to produce an amplified sEMG signal. A baseline drift suppression circuit in the signal acquisition device extracts a first low-frequency component from the amplified sEMG signal and performs subtraction processing between the amplified sEMG signal and the first low-frequency component to obtain a difference signal. A filter circuit in the signal acquisition device filters the difference signal to obtain a target acquisition signal. With introduction of baseline drift suppression in the signal acquisition circuit, the baseline drift caused by a low-frequency component in a sEMG signal is eliminated, and the stability of a target acquisition signal is enhanced.
