Single ramp analog to digital converter with feedback |
| abstract |
The ramp voltage of an analog to digital converter is started at a point below zero and the output of a pulse generator is gated into a counter when the ramp voltage passes through zero. The pulse generator gate is closed when the ramp voltage passes through an unknown analog voltage to be measured or a reference voltage. A calibration cycle is incorporated wherein a known reference voltage should be represented by a known number of pulses. When the number of pulses is too high, the pulse generator may be slowed down or the rate of increase of ramp voltage may be speeded up. If there are too few pulses, the pulse generator may be speeded up or the rate of change of ramp voltage may be slowed down. |
