FINE GRAIN POWER GATING - A simplified explanation of the abstract

This abstract first appeared for US patent application 20240322819 titled 'FINE GRAIN POWER GATING

The abstract of the patent application describes cells with integrated switches and/or clamps. In simple terms, a cell includes a circuit with an input and an output, a switch connected between a power supply and the circuit, and a clamp connected to the output of the circuit.

• The switch is designed to turn on when it receives an enable signal with a first logic value and turn off when the enable signal has a second logic value.
• The clamp is configured to limit or control the output of the circuit when the enable signal has the second logic value.

Potential Applications: - This technology could be used in electronic devices to control power flow and protect circuits from damage. - It may find applications in battery management systems to regulate charging and discharging processes.

Problems Solved: - Helps prevent overloading of circuits by providing a mechanism to control the output. - Enhances the overall efficiency and reliability of electronic systems.

Benefits: - Improved safety and protection for electronic components. - Enhanced performance and longevity of electronic devices.

Commercial Applications: Title: "Advanced Circuit Protection Technology for Electronic Devices" This technology could be utilized in consumer electronics, automotive systems, and industrial equipment to enhance safety and efficiency.

Questions about the Technology: 1. How does the integrated switch in the cell help in regulating power flow? - The integrated switch in the cell can be controlled by an enable signal to turn on or off, effectively managing the power flow within the circuit.

2. What are the potential advantages of using integrated clamps in electronic devices? - Integrated clamps can help protect circuits from damage by limiting the output when necessary, ensuring the longevity and reliability of the device.

Original Abstract Submitted

aspects of the present disclosure provide cells including integrated switches and/or integrated clamps. in some aspects, a cell includes a circuit having an input and an output, and a switch coupled between a supply rail and the circuit, wherein the switch is configured to receive an enable signal, turn on when the enable signal has a first logic value, and turn off when the enable signal has a second logic value. the cell also includes a first clamp coupled to the output of the circuit, wherein the first clamp is configured to clamp the output of the circuit when the enable signal has the second logic value.
