  • Analog-to-digital converter
    Patent number: 4325055
    Abstract: An analog-to-digital converter using MOS-charge redistribution techniques performs an N-bit analog-to-digital conversion with only N steps, using two capacitors. These capacitors enable obtaining at each step a reference voltage VRi=VR/2.sup.i and either to compute a voltage Vi+1=Vi-VRi if the i.sup.th bit is equal to 1 or to retain the voltage Vi+1=Vi if the i.sup.th bit is equal to 0. At each step, the voltage Vi is compared to the reference voltage VRi in order to determine the value of the i.sup.th bit.
