Abstract
Techniques and methods for reducing or preventing latch up in row decoder circuits are disclosed herein. An example apparatus may include an array of pixels, a row address decoder, and control circuitry. The row decode circuit including a plurality of decode circuits, each including at least two transistors having respective body terminals coupled to a first node. The control circuitry including a body biasing circuit coupled to the first node, the body biasing circuit to adaptively provide a bias voltage to the first node in response to an operating state of the imaging system and/or a change in one of two reference voltages based on a control signal provided by a bias control circuit.
