1Use of energy by moving object
If a conventional push-pull circuit is used to amplify differential signals, then signal amplification is achieved, but energy released to ground cannot be reused leading to poor energy utilization efficiency
Solution Approach 1:
The patent converts the harmful effect of energy being released to ground into a beneficial effect by capturing this released energy and redirecting it to power the other side of the differential signal. The energy that would normally be wasted is now reused to amplify the opposite signal, transforming energy loss into energy recovery and improving overall energy utilization efficiency
Solution Approach 2:
The patent merges the energy paths of the two differential signal sides by coupling the output of one side to the input of the other. This allows the energy released by one transistor to be directly utilized by the complementary transistor, creating a unified energy recycling system rather than two separate energy-consuming paths
