Abstract
Methods and systems for readout of charged couple devices include architecture for the output stage of a sensor such as a charge-coupled device. The architecture makes use of multiple serial amplifiers configured as a register, to reduce the noise of the pixel measurement without increasing the readout time of the sensor by parallel multiple readouts of the pixel information.
Claims20
A system comprising:
- a front end;
- and
- a plurality of readout stages wherein each of the plurality of readout stages are connected creating a serial readout register.
A readout method for comprising:
- receiving at least one photon on a detector;
- measuring a charge packet in a first of a plurality of readout stages;
- transferring the charge packet to a sequential readout stage among the plurality of readout stages;
- and
- determining a pixel value associated with the charge packet.
