AMPLIFIER CIRCUIT FOR ENABLING POWER EFFICIENT AND FASTER PIXEL SETTLING IN IMAGE SENSORS - A simplified explanation of the abstract
This abstract first appeared for US patent application 17567348 titled 'AMPLIFIER CIRCUIT FOR ENABLING POWER EFFICIENT AND FASTER PIXEL SETTLING IN IMAGE SENSORS
Simplified Explanation
The patent application describes a technology for a CMOS image sensor that includes a pixel circuit, a VSL circuit, and an amplifier. The pixel circuit generates a reset voltage and a signal voltage based on the power supply and the intensity of light captured by the pixel. The VSL circuit stores pixel information in a pixel load by settling the voltage at the pixel load to the signal voltage or the reset voltage. The amplifier generates a voltage by varying the resistance at its input to enable the VSL circuit to store the pixel information or set the voltage at the pixel load to the reset voltage.
- A CMOS image sensor with improved pixel circuit, VSL circuit, and amplifier.
- The pixel circuit generates reset and signal voltages based on power supply and light intensity.
- The VSL circuit stores pixel information in a pixel load by settling the voltage to the signal or reset voltage.
- The amplifier generates a voltage by varying resistance to enable pixel information storage or resetting the voltage.

Original Abstract Submitted
A Complementary Metal Oxide Semiconductor (CMOS) Image Sensor (CIS), includes a pixel circuit, a VSL circuit, and an amplifier. The pixel circuit may generate a reset voltage and a signal voltage, based on a power supply connected to the pixel circuit and/or intensity of light captured by the pixel circuit. The VSL circuit may store pixel information in a pixel load based on settling a voltage at the pixel load to the signal voltage and/or set the voltage at the pixel load to a pixel reset voltage based on settling the voltage at the pixel load to the reset voltage. The amplifier may generate a voltage, based on varying a resistance at an input of the amplifier, to enable the VSL circuit to store the pixel information and/or set the voltage at the pixel load to the pixel reset voltage.
