FIELD: neural amplifiers.
SUBSTANCE: present disclosure relates to a differential switched capacitor neural amplifier, for example, for use in an analogue artificial neural network. The switched capacitor differential neural amplifier comprises a sampling stage with a plurality of differential inputs for receiving a plurality of input voltages and with at least one pair of digitally adjustable charge stores for sampling a plurality of input voltages, a summing stage for summing the charges provided from the resulting plurality of input voltages, in order to generate a summing signal, with the summing stage connected downstream of the sampling stage, and the buffer and activation stage, which is configured to apply the activation function and generate a buffered output voltage at the differential output, based on the signal summation.
EFFECT: increase in the performance and flexibility of an analogue neural network.
