Abstract: Circuits for reflection cancellation in single-ended signaling are disclosed. A transmission circuit includes a control circuit configured to receive a plurality of input signals that include a plurality of symbols having at least one bit and a data driver circuit configured to generate a particular signal on a transmission medium using a particular symbol of the plurality of symbols. The transmission circuit further includes a reflection cancellation circuit configured to, after a generation of the particular signal, generate a reflection cancellation signal on the transmission medium using an inverted value of a different symbol of the plurality of symbols received prior to the particular symbol. A first composite of the particular signal and the cancellation signal is readable at a load as a value of the particular symbol, wherein the load is configured to receive a transmitted signal via the transmission medium.
