Abstract
A tracking analog-to-digital converter (ADC) which incorporates an input device, such as a superlattice, which produces a pulsating output current corresponding to the voltage level of an analog input voltage and an encoding device to provides a unique digital code which can be read to yield an approximation of the analog input voltage level. By simultaneously tracking the analog input voltage, the device operates at higher speeds than previously attainable. The resolution of the new ADC is increased by composing the input device to respond to narrow voltage ranges. When the input device is a superlattice, narrow response ranges are accomplished by composing the superlattice to have an increased number of resonances or by vertically stacking a plurality of superlattices.
