A line receiver including an analog-to-digital converter is described. The line receiver may include an input stage, a first sampling stage, an integration stage, and a second sampling stage. The input stage may be configured to receive an input voltage representative of a signal transmitted by a transmitter, and to convert the input voltage to a current. The input stage may include a trans-conductance stage. The current may be sampled using the first sampling stage. The sampled current may be converted to a voltage using the integration stage. The integration stage may include a trans-impedance stage. The voltage obtained using the integration stage may be sampled using the second sampling stage.
