Abstract:
1. A threshold detector system receiving an input signal having values represented by only a low range or a high range, the low range and the high range being non-overlapping, the low range comprising values between a first threshold and a second threshold, and the high range comprising values between a third threshold and a fourth threshold, the threshold detector system comprising: a detector circuit that receives the input signal and that generates a logic output, the logic output being a logic low value when the input signal values are in the low range and a logic high value when the input signal values are in the high range; a bias circuit, coupled to the detector circuit, that generates first and second bias signals for biasing the detector circuit; and a supply circuit that provides a supply voltage to the detector circuit and the bias circuit, wherein the first bias signal is fixed at a first desired value below the supply voltage, and the second bias signal is fixed at a second desired value above a minimum voltage.
