OPERATIONAL AMPLIFIER, DRIVE CIRCUIT, INTERFACE CHIP, AND ELECTRONIC DEVICE - A simplified explanation of the abstract

This abstract first appeared for US patent application 18345921 titled 'OPERATIONAL AMPLIFIER, DRIVE CIRCUIT, INTERFACE CHIP, AND ELECTRONIC DEVICE

Simplified Explanation

The abstract describes a patent application related to power electronics technologies.

  • The patent application involves an operational amplifier, a drive circuit, an interface chip, and an electronic device.
  • The operational amplifier includes various components such as load resistors, switching transistor groups, and a tail current source.
  • The first switching transistor group is connected to the operational amplifier's first output end and a power supply through a load resistor, and its second end is grounded using the tail current source.
  • The second switching transistor group is connected to the operational amplifier's second output end.
  • The patent application aims to provide a simplified explanation of the operational amplifier's design and its connection to other components.


Original Abstract Submitted

An operational amplifier, a drive circuit, an interface chip (), and an electronic device () relate to the field of power electronics technologies. The operational amplifier includes a first load (R), a second load (R), a first switching transistor group (-), a second switching transistor group (-), and a tail current source (). The first switching transistor group (-) has a first end connected to a first output end (outp) of the operational amplifier and connected to a power supply (VDD) of the operational amplifier by using the first load (R), and has a second end grounded by using the tail current source (). The second switching transistor group (-) has a first end connected to a second output end (outn) of the operational amplifier.
