Abstract:
1. A method for improving resolution of a current mode driver, where the current mode driver is operable to provide an output that falls within a predetermined range, the method comprising: sensing at least one of a process condition, a voltage condition and a temperature condition with a PVT detector; adjusting a full scale current of a DAC in accordance with an output of the PVT detector; and setting a current control signal based on an output of the DAC, the current control signal being applied to the current mode driver to improve resolution of the current mode driver, wherein the current control signal for transistors in the current mode driver includes a plurality of bits; wherein the sensing comprises; applying a PVT independent current to a PVT sensitive load; and detecting a voltage drop across the PVT sensitive load.
