Receiver circuit

Abstract

A receiver circuit, comprising: an receiver-input-terminal configured to receive input-signalling; an receiver-output-terminal configured to provide output-signalling; a plurality of sub-receivers, each configured to compare the received input-signalling with a different effective threshold value in order to provide a digital sub-receiver-output-signal, wherein the different effective threshold values have weighted values in a sequence between a least significant value and a most significant value; a controller configured to, in response to detecting calibration-signalling at the receiver-input-terminal: process the digital sub-receiver-output-signals in order to identify the sub-receiver with the most significant effective threshold value that is triggered by the calibration-signalling as a triggered-sub-receiver; identify a preceding-sub-receiver as the sub-receiver that has an effective threshold value that is before that of the triggered-sub-receiver in the sequence of weighted effective threshold values; and configure the receiver circuit such that, for subsequent signal processing, the sub-receiver-output-signal from the preceding-sub-receiver is provided to the receiver-output-terminal.
