A charge domain filter (CDF) and a bandwidth compensation circuit of the CDF are provided. The CDF includes an amplifier, a plurality of switch-capacitor networks (SCNs), a connector, a current adder (CA) and a bandwidth compensation circuit. A first input terminal of the amplifier receives an input signal, and an output terminal thereof is connected to input terminals of the SCNs. The connector is connected between the output terminal of the SCNs and the CA for configuring coupling status of the output terminals of the SCNs and input terminals of the CA. The bandwidth compensation circuit senses a portion of or all of the output terminals of the SCNs and the CA, and outputs the sensing result to a second input terminal of the amplifier. |
