Systems and methods to implement a multiply and accumulate (MAC) unit is described. In an example, a device can include a first current mode digital-to-analog converter (DAC) configured to multiply an input signal with a first current having a first amplitude to generate a first signal. The device can further include a second current mode DAC configured to multiply the input signal with a second current having a second amplitude to generate a second signal. The second amplitude can be less than the first amplitude. The device can further include a mixer configured to multiply the second signal with a clock signal to generate a third signal. The third signal can be combined with the first signal via a current summing node to generate an output signal. The output signal can be outputted to another device.
