... On-chip output MOSFET for low noise . ... Serial-parallel- . ... The signal charge collected in the imaging array is transferred along the columns, one row at a time, to one or both of the serial registers and from there to the desired output amplifiers. ... Timing . ... Likewise, the parallels, P1a, P1b, P2a, P2b, P3a, P3b, TGa and TGb should all be clocked according to OUTa and OUTb parallel timing, and the lower half parallel and serial clocks would be clocked according to OUTc and OUTd timing. ...
