SEMICONDUCTOR DEVICE - A simplified explanation of the abstract
This abstract first appeared for US patent application 18605854 titled 'SEMICONDUCTOR DEVICE
Simplified Explanation:
This semiconductor device includes a reference voltage generation portion, a bias current supply portion, and a controller. The controller compares the power supply voltage with a set threshold voltage based on the reference voltage and adjusts the bias current accordingly.
- The semiconductor device generates a reference voltage.
- The bias current supply portion includes two current supply portions.
- The controller adjusts the bias current based on the comparison of the power supply voltage with the set threshold voltage.
- When the power supply voltage is higher than the threshold, only the first current supply portion is used for bias current.
- When the power supply voltage is lower than the threshold, both current supply portions are combined for bias current.
Potential Applications: - This technology can be used in various analog circuits that require precise bias current control. - It can be applied in sensor devices, amplifiers, and other electronic systems where stable bias current is crucial.
