Abstract
In one embodiment, a method includes generating a current that is proportional to a mobility and an oxide capacitance of a tracking device and independent of a threshold voltage variation of the tracking device, generating a voltage from the current, and providing the voltage as at least part of a bias voltage for another device. In one embodiment, this other device may be a compensation circuit coupled to a main device to compensate for capacitance non-linearity of the main device.
