Abstract
A column-parallel dual-gain single-slope ADC comprises an input for receiving a signal V, a sample-and-hold stage which receives Vand outputs sampled signal V, a comparator, a counter, and a ramp generator which generates high-gain (HG) and low-gain (LG) ramps, with the ratio of the LG ramp slope to the HG ramp slope being greater than 1. During a coarse conversion phase, Vis compared with a threshold voltage V, and a flag is set to a first or second state depending on the comparison. During a fine conversion phase, if the flag is in the first state, the HG ramp is provided to the comparator and its output toggles when the ramp voltage becomes equal to V. If the flag is in the second state, the LG ramp is provided to the comparator and its output toggles when the LG ramp voltage becomes equal to V.
