ABSTRACT:
A signal processing device includes a conversion device configured to output a differential current signal at two taps on the basis of an input signal and an oscillator signal. A respective controllable current source is coupled to one of the two taps. An amplification device having a current signal input has a first connection to the first tap and a second connection coupled to the second tap of the conversion device. The amplification device has two output taps; a first charge store is connected to a connection of the amplification device and to the second tap of the amplification device, and a first resistive load is connected in parallel with said first charge store. A second charge store is connected to the second connection of the amplification device and to the first tap of the amplification device, and a second resistive load is connected in parallel with said second charge store.
