Electronic Devices & CircuitsCurrent Mirrors

Compared with a simple current mirror, a cascode current mirror is mainly used to obtain?

  • AHigher output resistance and better current-source behavior
  • BLower input resistance only
  • CZero supply voltage
  • DA square-wave output
Report an error
Correct Answer: A. Higher output resistance and better current-source behavior
Explanation: The cascode arrangement reduces the effect of output-voltage variation on mirrored current, substantially increasing output resistance.
Reference: Standard analog electronics: cascode current mirror
