<p>1526137 Analogue to digital converter THOMSON-CSF 29 Sept 1976 [2 Oct 1975] 40507/76 Heading H3H In an a-d converter of the type wherein a local reference ramp 1 is compared 8 with an input sample 2 and pulses are counted 10 during description of the ramp the input is sampled by integrating means comprising a charge transfer device having p+q stages, the analogue signal being connected to the device input for the initial p clock pulses and a fixed voltage (e.g. 0) being connected to the input during the q clock pulses of ramp generation. The ramp generator which produces a compression low ramp may also be constructed from a C.T.D. with the compression being effected by weighted electrode areas.</p> |
