  • Publication number: 20110298385
    Abstract: Disclosed are controllable drive circuits for powering an organic light emitting diode (OLED) or other electronic load. According to one implementation, a circuit structure is provided that applies a pulse width modulated (PWM) drive current to an OLED. The time-average drive current to the OLED can be modulated in accordance with a periodically sampled control signal. In turn, the luminance of the OLED can be suitably varied over a control range. Circuit structures provided may be fabricated at least in part on a common substrate such that respective integrated circuit devices are defined. In one or more implementations, at least a portion of drive circuits may be fabricated within a 65 nanometer (or smaller) environment.

  • Patent number: 7961129
    Abstract: An apparatus and method for reducing error in converting a multi-bit signal to a single bit signal. An analog delta-sigma modulator receives an analog signal and converts it to a multi-bit digital signal that is provided to a digital delta-sigma modulator. The digital delta-sigma modulator introduces error by converting the multi-bit signal to a single-bit signal. The error from the conversion is fed back to the analog delta-sigma modulator which incorporates the error information into the analog signal before it is converted to a multi-bit digital signal.
