1. A circuit comprising:
a first transfer transistor connecting a photodiode to a floating diffusion node, wherein the first transfer transistor is individually selectable by a combination of:
(i) a first transfer select input; and
(ii) a second transfer select input;
a reset transistor connected between one or more potentials and the floating diffusion node, wherein the reset transistor is individually selectable by a combination of:
(i) a first reset select input; and
(ii) a second reset select input;
a first reset selection transistor having a gate terminal connected to (i) the first reset select input or (ii) the second reset select input, and the first reset selection transistor also being connected between (1) a gate terminal of the reset transistor and (2) the other of (a) the first reset select input or (b) the second reset select input;
an output transistor in a source-follower configuration with a gate connected to the floating diffusion node; and
a selection transistor connected to the output of the output transistor.
