Abstract
Systems, methods, and apparatuses that may be employed to reduce noise in an electronic circuit are described. Systems are provided that include a circuit, wherein the circuit is configured to provide an active reset technique and an active column sensor readout technique. Methods for reducing circuit noise are also provided. The methods include providing a circuit configured to perform an active reset technique and an active column sensor readout technique. The methods further provide that the active reset technique and the active column sensor readout technique are both performed by the circuit. An imaging apparatus is provided that includes an array of photo-sensitive pixels, wherein each of the pixels can include a circuit configured to provide an active reset technique and an active column sensor readout technique. The active reset technique and the active column sensor readout technique are executable on the circuit.
