Abstract: An integrated circuit (IC) based detection circuit for determining a strap value and a method of detecting a digital strap value. In one embodiment, the detection circuit includes: (1) a first receiver including transistors having first electrical characteristics that define a first threshold for the first receiver, the first receiver operable to generate a first binary digit based on an input signal and the first threshold and (2) a second receiver including transistors having second electrical characteristics that differ from the first electrical characteristics and define a second threshold for the second receiver that is lower than the first threshold, the second receiver operable to generate a second binary digit based on the input signal and the second threshold, the first and second binary digits indicating whether the strap value lies above the first threshold, between the first and second thresholds or below the second threshold.
