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:
