A semiconductor circuit comprising an input block having a first chopper providing a chopped voltage signal, a first transconductance converting said chopped voltage signal into a chopped current signal, a second chopper providing a demodulated current signal, a current integrator having an integrating capacitor providing a continuous-time signal, a first feedback path comprising: a sample-and-hold block and a first feedback block, the first feedback path providing a proportional feedback signal upstream of the current integrator. The amplification factor is at least 2. Charge stored on the integrating capacitor at the beginning of a sample period is linearly removed during one single sampling period. Each chopper operates at a chopping frequency. The sample-and-hold-block operates at a sampling frequency equal to an integer times the chopping frequency.
