Abstract
A receiving circuit may include an amplifier. The amplifier may include a first amplification circuit and a second amplification circuit. The first amplification circuit may be configured to differentially amplify a first input signal and a reference signal and configured to generate output signals. The second amplification circuit may be configured to differentially amplify a second input signal and the reference signal and configured to generate the output signals.
