SEMICONDUCTOR DEVICE - A simplified explanation of the abstract
This abstract first appeared for US patent application 18045578 titled 'SEMICONDUCTOR DEVICE
Simplified Explanation
The patent application describes a semiconductor device that includes multiple pulse width modulation circuits. These circuits have specific components such as inverters and NOR gates to perform certain operations on clock signals and logic signals.
- The pulse width modulation circuits consist of a first inverter, a NOR gate, and a second inverter.
- The first inverter inverts clock signals and outputs a first inversion signal.
- The NOR gate performs a NOR operation on the first inversion signal and a first logic signal, producing a second logic signal.
- The second inverter then inverts the second logic signal and outputs a second inversion signal.
- Two adjacent pulse width modulation circuits have a phase delay between their clock signals, and the first logic signal of one circuit is the second logic signal of the other circuit.
Potential applications of this technology:
- Power electronics: Pulse width modulation is commonly used in power converters and inverters to control the output voltage or current.
- Motor control: Pulse width modulation can be used to control the speed and direction of motors.
- Communication systems: Pulse width modulation can be used in data transmission and modulation techniques.
Problems solved by this technology:
- Efficient control: The described circuitry allows for precise control of pulse width modulation signals, enabling efficient power conversion and motor control.
- Phase synchronization: The phase delay between adjacent circuits ensures proper timing and synchronization of the pulse width modulation signals.
Benefits of this technology:
- Improved efficiency: The precise control of pulse width modulation signals can lead to more efficient power conversion and motor control, reducing energy losses.
- Enhanced performance: The phase synchronization between circuits ensures accurate timing, minimizing errors and improving overall system performance.
