Abstract
An image sensor may include an array of image pixels arranged in rows and columns. Each column of pixels may be coupled to current source transistors and capacitance cancellation circuitry. The capacitance cancellation circuitry may include capacitors, a common source amplifier transistor, an autozero switch, a switch for selectively deactivating at least one of the capacitors during sample-and-hold reset and sample-and-hold signal operations.
