Abstract
An arrangement for charge integration comprises a charge-generating circuit (2) that provides a charge-dependent signal, and a coupling circuit (20) comprising a first and a second transistor (T1, T2). The first transistor (T1) can be controlled in dependence on the charge-dependent signal. The second transistor (T2) is configured to forward the charge-dependent signal in dependence on a control signal provided by the first transistor (T1). The forwarded charge-dependent signal is integrated by an integrator (30).
