A charge transfer circuit includes input terminals (68, 72) for receiving input electrical charges (Q in 1, Q in 2), transconductance amplifiers (G1, G2) having first and second inputs including inverting inputs, and first and second differential current outputs (In1, Ip1, or In2, Ip2), and a multiple output stage circuits responsive to the differential current outputs for producing two or more electrical current output signals (Ia1, Ib1, or Ia2, Ib2) whose values are related to the values of the differential current outputs and to each other. Also included are feedback loops (If1, If2) for delivering one of the electrical current putput signals to the inverting inputs of the transconductance amplifiers, and integrators (76, 80) for integrating others of the electrical current output signals to produce output electrical charges (Qo1, Qo2) whose values are related to the values of the input electrical charges.
