Chopper stabilization in a precision amplifier is mainly used to reduce?

  • AInput offset and low-frequency 1/f noise
  • BHigh-frequency carrier power only
  • COutput load current
  • DSupply voltage requirement to zero
Report an error
Correct Answer: A. Input offset and low-frequency 1/f noise
Explanation: Chopper techniques modulate low-frequency signals away from the region dominated by offset and flicker noise, then demodulate them after amplification.
Reference: Standard analog electronics: chopper stabilization
