How does slew limiting differ from clipping in its cause?

  • A.One depends on frequency, the other on temperature
  • B.One affects only sine waves, the other only square waves
  • C.One is a rate limit, the other an amplitude limit
  • D.One occurs at the input, the other at the output

Answer: C

Slew limiting is a limit on how fast the output can change, set by an internal current and a capacitance, while clipping is a limit on how far it can go, set by the supply rails. Both occur at the output, neither is a temperature effect, and both affect any waveform. The distinction matters practically because the remedies differ entirely: a faster amplifier for one, a higher supply or a smaller signal for the other. A limit that survives making every external component ideal is an intrinsic one, and worth knowing for that reason.
