- **Caution**: 

### Q: What is the primary function of a push-pull output stage in gate driver ICs?
**A**: The push-pull output stage serves as the final amplification stage that delivers high-current, low-impedance switching signals directly to power semiconductor gates, enabling efficient switching with minimal signal distortion.

### Q: What materials are typically used in manufacturing push-pull output stages?
**A**: These stages are primarily fabricated using silicon for integrated transistors (PMOS and NMOS) and metal interconnects such as aluminum or copper for electrical connections within the integrated circuit.

### Q: How does the push-pull configuration benefit power semiconductor driving?
**A**: The push-pull configuration uses complementary PMOS and NMOS transistors to actively drive signals both high and low, providing fast switching speeds, reduced crossover distortion, and improved efficiency when driving capacitive loads like power semiconductor gates.
