Multiply and accumulate using current division and switching

Abstract:

System and methods for implementing a multiply and accumulate (MAC) operation are described. In an example, a device can multiply an input digital signal with an input current to generate a current signal. The device can further divide the current signal into a plurality of currents. The device can further sample the plurality of currents sequentially using the same clock frequency. The device can further combine the plurality of sampled currents to generate an output current signal.
