ABSTRACT:
A bridge amplifier is provided wherein one end of a load device is driven by a first amplifier and the other end of the load device is driven by a second amplifier. The second amplifier is an inverting amplifier comprising P and N-channel field-effect transistors, having complementary symmetry conduction characteristics. The input to the second amplifier is directly coupled to the output of the first amplifier.
