| 1. An analog-to-digital converter comprising:
floating-gate transistors having floating gates to store respective charge levels and having gate terminals to output respective
reference voltages that correspond to the charge levels stored at the floating gates; and
voltage comparators each having a first input coupled to a common input signal node to receive an analog input signal and
each having a second input coupled to the gate terminal of different floating-gate transistors to receive the reference voltage
therefrom such that each voltage comparator is coupled to one corresponding floating-gate transistor.
