| 1. A quantization circuit comprising:
a sense resistor configured to provide a voltage that is indicative of a digital quantization of an input voltage;
a plurality of resonant tunneling diodes (RTDs) arranged in series between the input voltage and the sense resistor; and
a sequencing circuit arranged in parallel with the plurality of RTDs and configured to conduct a portion of a current flowing
between the input voltage and the sense resistor to define a sequential order of triggering of the plurality of RTDs in response
to a given magnitude of the input voltage.
