Abstract
In an ultra-wideband communication system, a 1-trit ternary analog-to-digital converter ('ADC') having dynamic threshold adaption and providing an output in ternary form [+1, 0, −1]. The ternary ADC includes a pair of 1-bit binary ADCs, one being configured in a non-inverting form, and one being configured in an inverting form. Each binary ADC includes an feedback network mechanism, thereby allowing for simultaneous and independent adaptation of the pair of thresholds, compensating for the effects of any DC offset that may be present. The use of a trit-based ternary encoding scheme improves system entropy.
