Samsung patents image sensor design with extra voltage boosters

Samsung has been granted a patent for an image sensor that includes specific circuits called boosting drivers. These drivers adjust the voltage of signals coming from the sensor's pixels before the data is converted into a digital image.

Why it mattersThis is a routine hardware improvement that helps manage signal strength in camera chips, which is standard work for phone manufacturers.

In the filing’s own words

An image sensor comprises a row driver, a first row line which is connected to the row driver, first to fourth pixels connected to the first row line, first to fourth column lines connected to the first to fourth pixels and configured to receive respective first to fourth output signals from the first to fourth pixels, a boosting circuit connected to the first to fourth column lines, a second row line connected to the boosting circuit, first and second boosting drivers connected, respectively, to first and second terminals of the second row line. The boosting circuit may adjust voltage of the first and second output signals based on a first boosting enable signal received from the first boosting driver and may adjust a voltage of the third and fourth output signals based on a second boosting enable signal received from the second boosting driver.

What exactly they claim (claim 1)

1. An image sensor, comprising: a first row driver; a first row line connected to the first row driver; a first pixel connected to the first row line; a second pixel connected to the first row line and spaced apart from the first pixel; a first column line connected to the first pixel; a second column line connected to the second pixel and different from the first column line; a second row line different from the first row line; a first boosting driver connected to a first terminal of the second row line; a second boosting driver connected to a second terminal of the second row line; a first boosting circuit connected to the first column line and the second row line; a second boosting circuit connected to the second column line and the second row line; a first analog-digital converter (ADC) connected to the first column line; and a second ADC connected to the second column line and spaced apart from the first ADC.
