CIRCUIT AND METHOD TO ENHANCE EFFICIENCY OF SEMICONDUCTOR DEVICE - A simplified explanation of the abstract

This abstract first appeared for US patent application 18360849 titled 'CIRCUIT AND METHOD TO ENHANCE EFFICIENCY OF SEMICONDUCTOR DEVICE

Simplified Explanation

The patent application describes a method of operating a circuit that includes an operational amplifier, sampling switches, holding switches, and combined switches.

  • The method involves four phases of operation.
  • In the first phase, the sampling switches are closed, the holding switches are open, and the combined switches are open.
  • In the second phase, the combined switches are closed.
  • In the third phase, the sampling switches are open, the holding switches are closed, and the combined switches are open.
  • In the fourth phase, the sampling switches are open, the holding switches are closed, and the combined switches are closed.


Original Abstract Submitted

A method of operating a circuit includes providing the circuit, the circuit includes an operational amplifier, a plurality of sampling switches, a plurality of holding switches, and a plurality of combined switches. The method further includes: during a first phase, causing the plurality of sampling switches to be closed, the plurality of the holding switches to be open, and the plurality of combined switches to be open; during a second phase, causing the plurality of combined switches to be closed; during a third phase, causing the plurality of sampling switches to be open, the plurality of the holding switches to be closed, and the plurality of combined switches to be open; and during a fourth phase, causing the plurality of sampling switches to be open, the plurality of the holding switches to be closed, and the plurality of combined switches to be closed.
