Abstract
An image sensor may include an array of imaging pixels and row control circuitry that provides control signals to the array of imaging pixels. In order to enable the row control circuitry to provide control signals to the array of imaging pixels that have a voltage greater than the power supply voltage, the row control circuitry may include voltage booster circuitry. The voltage booster circuitry may include two amplifiers and may be operable in three different modes. In the first mode, only the second amplifier may be enabled and the output voltage may be between 0V and 2.0V. In the second mode, both the first and second amplifiers may be enabled and the output voltage may be between 2.0V and 2.8V. In the third mode, only the first amplifier may be enabled and the output voltage may be between 2.8V and 4.0V.
