  • Non-linear capacitance compensation
    Patent number: 8907727
    Abstract: Embodiments are directed to capacitance compensation via a compensation device coupled to a gain device to compensate for a capacitance change occurring due to an input signal change, along with a controller coupled to the compensation device to receive the input signal and to control an amount of compensation based on the input signal. In some embodiments, banks may be formed of multiple compensation devices, where each of the banks has a different size and is coupled to receive a different set of bias voltages.

  • Generating a process and temperature tracking bias voltage
    Patent number: 8219049
    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.
