* Question
| What is the working principle of the OTL circuit? |
* Answer
| Complementary symmetrical power amplifiers are also known as OTL circuits (no output transformer push-pull power amplifiers).The main advantage of this circuit is that it eliminates the cumbersome input transformer and output transformer, and has wide frequency response, small distortion and large output power, which is beneficial to miniaturization and integration, and is widely used. |
