Disclosed are a sampling circuit and a receiver with which filter characteristics compatible with the reception of wideband signals can be realized with a high degree of freedom in the setting of the filter characteristics. More specifically, a sampling circuit capable of removing adjacent interfering wave signals while keeping in-band deviation small is disclosed. The sampling circuit (100) is equipped with a discrete-time analog processing circuit group (101) wherein multiple discrete-time analog processing circuits are connected in parallel, a synthesizer (102) which synthesizes the output signals from each of the circuit systems and outputs same, and a digital control unit (103) which outputs control signals. Each of the discrete-time analog processing circuits (101-1-101-n) is configured to include multiple rotate capacitor units (1014) which each includes a main rotate capacitor (10144) and a sub-rotate capacitor (10143), and only the main rotate capacitors (10144) share electric charge with a buffer capacitor (1022) included in the synthesizer (102).
