The amplifier load current cancellation in a current integrator comprises applying an input current (Ιin) to an operational transconductance amplifier provided with an integration capacitor (Cint) for current integration, leading an output current (Iout) of the operational transconductance amplifier through a sensing resistor (Rsense) t thus producing a voltage drop over the sensing resistor, generating a cancellation current (Iout,cancel) dependent on the voltage drop over the sensing resistor, and injecting the cancellation current to the output current, before or after the output current passes the sensing resistor, thus eliminating a dependence of the output current on the input current.
