A differential charge and dump optoelectronic receiver for baseband digital optoelectronic data links is disclosed having a preamplifier and a voltage controlled current source that defines the tail current of a differential pair functioning as a two quadrant multiplier, and using capacitors as loads on the differential pair making said differential pair an integrator. The integrator provides a full differential output, part of which is fedback to control the gain of the preamplifier. In a preferred embodiment, one integrator pair is used to recover the data from a Manchester encoded data stream. In another preferred embodiment, two pairs of integrators are used for QPSK like codes.
