  • High output amplifier for stable operation
    Patent number: 6741133
    Abstract: A high output amplifier includes a comparison amplifier having a first input, a second input, and an output, wherein a set voltage is applied to the first input, a voltage of the output is coupled to the second input, and the output is generated in response to a difference between the voltage applied to the first input and the voltage coupled to the second input. The high output amplifier also includes a low-pass filtering device that receives and performs low-pass filtering on the output of the comparison amplifier, a conversion device that converts the output of the low-pass filtering device to complementary signals, and a push-pull output device, driven by the complementary signals, that supplies electrical current to a load, wherein an increase in the electrical current supplied by the push-pull output device is decreased by changes in the load due to the low-pass filtering device.
