Questions & Step-by-Step Solutions

In small-signal analysis, what does the term 'transconductance' refer to?
  • Step 1: Understand that transconductance is a term used in electronics.
  • Step 2: Know that it relates to how a device (like a transistor) can control current.
  • Step 3: Recognize that in small-signal analysis, we look at small changes in voltage and current.
  • Step 4: Learn that transconductance is calculated by taking the output current and dividing it by the input voltage.
  • Step 5: Remember that a higher transconductance means the device is better at controlling current with a small change in voltage.
