  • Frequency response compensation in a digital to analog converter
    Patent number: 9319060
    Abstract: A digital-analog converter (DAC) comprises a receiving circuit configured to receive an input bit stream and generate a first bit signal stream of the input bit stream, a first delay circuit coupled to the receiving circuit to receive the first bit signal stream and to generate a second bit signal stream representing a delayed version of the first bit signal stream. The DAC also comprises a first current generation circuit to receive the first bit signal stream, the first current generation circuit configured to provide first current, corresponding to the first bit signal stream, to a first output. The DAC further comprises a second current generation circuit to receive the second bit signal stream and to provide second current to the first output responsive to receiving the second bit signal stream, a waveform of the second current inverted and scaled relative to a waveform of the first current.
