The desirable characteristics of a transconductance amplifier are

1. high input resistance and high output resistance
2. high input resistance and low output resistance
3. low input resistance and high output resistance
4. low input resistance and low output resistance

Correct answer: high input resistance and high output resistance

Solution

A transconductance amplifier should have high input resistance to minimize loading effects on the preceding stage and high output resistance to ensure that it can effectively drive the load without significant voltage drop.
