Patent ID: 7843502

Claim:
An apparatus for generating a boost signal to a pixel array that includes a plurality of rows, the apparatus comprising: a first input that receives at least one programming control signal; a second input that receives a reference signal; an output; a first capacitor having a first node and a second node, the first node being coupled to the second input, the second node being connected to the output;. at least one second capacitor having a first node and a second node, the second nodes of the at least one second capacitor being directly connected to the second node of the first capacitor; a switching circuit controllable by the reference signal, the switching circuit having at least a first mode and a second mode, wherein when the switching circuit is in the first mode, the first node of the first capacitor is not connected to the first node of the at least one second capacitor, and wherein when the switching circuit is in the second mode, the first node of the first capacitor is directly connected to the first nodes of the at least one second capacitor.
