Abstract
In certain embodiments, a unit cell is provided. The unit cell may include a high sensitivity path and a low sensitivity path. The high sensitivity path may include a first transistor and a first switch. The first switch may couple an output node to the first transistor. The low sensitivity path may include a capacitor. A second switch may couple the high sensitivity path to the low sensitivity path. A third switch may couple the high sensitivity path and the low sensitivity path to a voltage node.
