LEVEL SHIFTER AND SEMICONDUCTOR DEVICE INCLUDING THE SAME - A simplified explanation of the abstract
This abstract first appeared for US patent application 18350640 titled 'LEVEL SHIFTER AND SEMICONDUCTOR DEVICE INCLUDING THE SAME
Simplified Explanation
The abstract describes a level shifter that takes an input signal swinging between a reference voltage and a first power supply voltage, and outputs a signal swinging between a second power supply voltage and a third power supply voltage. The level shifter includes a tolerant circuit to limit the output voltage within a specific range.
- Input circuit receiving input signal swinging between reference voltage and first power supply voltage
- Output circuit outputting signal swinging between second power supply voltage and third power supply voltage
- Tolerant circuit limiting output voltage range between reference voltage and second power supply voltage
Potential Applications
The level shifter can be used in various electronic devices and systems that require signal level shifting, such as communication systems, data transmission systems, and sensor interfaces.
Problems Solved
1. Signal compatibility: The level shifter solves the problem of mismatched signal levels between different components or subsystems. 2. Signal integrity: By limiting the output voltage range, the level shifter ensures the integrity of the signal throughout the shifting process.
Benefits
1. Signal accuracy: The level shifter maintains the accuracy of the input signal during the level shifting process. 2. Versatility: The level shifter can be used in a wide range of applications due to its flexible voltage range capabilities.
Potential Commercial Applications
"Level Shifter for Signal Processing in Electronic Devices"
Possible Prior Art
Prior art may include existing level shifting circuits or devices used in electronic systems for signal processing and communication purposes.
Unanswered Questions
How does the tolerant circuit ensure the output voltage stays within the specified range?
The tolerant circuit likely includes voltage regulation components to monitor and adjust the output voltage as needed to maintain it within the desired range.
What are the specific voltage levels of the first, second, and third power supply voltages in this level shifter?
The abstract does not provide specific details on the voltage levels of the power supplies used in the level shifter. Additional information would be needed to determine these values.
Original Abstract Submitted
A level shifter includes: an input circuit receiving an input signal swinging between a reference voltage and a first power supply voltage having a level higher than a level of the reference voltage; an output circuit outputting an output signal swinging between a second power supply voltage having a level higher than the level of the first power supply voltage and a third power supply voltage having a level higher than the level of the second power supply voltage; and a tolerant circuit connected between the input circuit and the output circuit, and configured to limit an output voltage of the input circuit to a range between the reference voltage and the second power supply voltage.
