Abstract
Receiver circuits for differential and single-ended signals are disclosed. In some embodiments, a receiver may include a first amplifier configured to receive a first signal of a differential pair of signals at a first input and a second signal of the differential pair of signals at a second input when operating in differential mode. The receiver may also include a second amplifier coupled to the first amplifier, where the second amplifier is configured to receive a reference signal at a third input and a single-ended signal at the first input when operating in single-ended mode. In some embodiments, several receivers may be used, for example, to process a differential clock signal and one or more single-ended data signals referenced to the clock signal and/or differential data signals referenced to a single-ended clock signal. In some embodiments, the delays of each signal propagating through each respective receiver may be independently adjusted.
