Abstract
A data communications receiver including a receiver coil, a first amplification stage coupled to the receiver coil, the first amplification circuitry to differentially amplify at least part of signal received by the receiver coil relative to a threshold, a second amplification stage coupled to receive the differentially amplified signal from the first amplification stage, the second amplification stage comprising a current mirror, and hysteretic level shifting circuitry to shift a level of part of the signal received by the receiver coil, the threshold or part of the signal received by the receiver coil and the threshold such that, in response to the at least part of the signal received by the receiver coil having crossed the threshold, a threshold crossing in the other direction is delayed.
