Novel analog-digital converters using voltage inverter switches. II. applications

For pt.I see ibid., vol.38, no.6, p.582-589 (1991). The use of voltage inverter switches (VIS) in analog-to-digital converter (ADC) circuits is described. In the first part of this paper VIS circuits were introduced, and their use in voltage reference circuits was demonstrated. In this second part, these reference circuits are incorporated into novel ADC circuits. Six different circuits are presented and analyzed; the principles on which these are based are the two-capacitor array, the algorithmic principle, the incremental principle, and the delta-sigma principle. The simulation of these circuits shows that the use of the VIS reference circuits leads to improved performance over current circuits. The circuits are based on CMOS technology and are wholly realizable on silicon.<
