  • Thermometric-R2R combinational DAC architecture to improve stimulation resolution
    Patent number: 11648400
    Abstract: The disclosure describes an implementation of a combinational thermometric-R2R that includes a thermometric DAC circuit to output the coarse output steps, an R2R circuit to control the fine output steps, and a resistor in series with the thermometric and R2R circuits. The techniques of this disclosure implement a fine resolution DAC, on the order of two nanoamps per bit, that operates at low current, yet maintains monotonicity throughout the DAC output range.
    Type: Grant
