The discrete-time receiver system includes: a voltage current conversion device low-noise-amplifying an input voltage signal, and converting the amplified signal into a current signal; a first filter performing IIR filtering on the current signal output from the voltage current conversion device; a discrete-time filter performing FIR filtering on a signal output from the first filter; and a second filter performing IIR filtering on a signal output from the discrete-time filter, wherein the discrete-time filter includes a plurality of current supply units generating a current having a size obtained by multiplying an input current by a determined gain, respectively, an adding unit adding currents supplied from the plurality of current supply units, and a plurality of controllers connecting the plurality of current supply units and the adding unit and controlling the flow of current supplied from the current supply units to the adding unit.
