Abstract
Image sensors with improved negative pump voltage settling, and circuitry for the same, are disclosed herein. In one embodiment, a power supply settling circuit includes a negative charge pump and a reference voltage generator. An output of the negative charge pump is selectively coupled to a first node of the negative pump settling circuit via a first switch, and an output of the reference voltage generator is selectively coupled to a second node of the negative pump settling circuit via a second switch. The first node is further selectively coupled to ground via a third switch, and the second node is further selectively coupled to ground via a fourth switch. The first node can additionally be coupled to a first pad, and the second node can additionally be coupled to a second pad. The pads can each be coupled to a capacitor, such as an off-chip capacitor.
