Assignee:

Marvell International Ltd. - Hamilton

International Classification:

H03M 1/34

US Classification:

341164, 341118, 341120, 341155, 341165

Abstract:

In one embodiment, a method receives an analog input voltage. The method also receives a threshold from a plurality of thresholds. A comparator performs a comparison of the input voltage with the received threshold and outputs an output value based on the comparison of the analog input voltage with the received threshold. The output value is for converting the analog input voltage to a digital value. The method determines if the threshold should be adjusted based on the comparison and adjusts the threshold when it is determined the threshold should be adjusted.

International Classification:

H03M 1/12

US Classification:

341172, 341161

Abstract:

Methods and systems are described for providing an analog-to-digital converter that uses reduced power and supply voltage. The analog-to-digital converter includes a sample phase configured to sample an incoming analog signal having an input signal range and compare the incoming analog signal to a reference voltage. The analog-to-digital converter also includes a feedback phase wherein the feedback phase receives sampled signal data corresponding to the incoming analog signal from the sample phase and is configured to produce an output signal comprising an output signal range, wherein the output signal range is equal to one half of the input signal range, and wherein the analog-to-digital converter has a feedback factor that is substantially greater than ⅓.

Abstract:

A display may have an array of pixels each of which has a light-emitting diode such as an organic light-emitting diode. A drive transistor and an emission transistor may be coupled in series with the light-emitting diode of each pixel between a positive power supply and a ground power supply. The pixels may include first and second switching transistors. A data storage capacitor may be coupled between a gate and source of the drive transistor in each pixel. Signal lines may be provided in columns of pixels to route signals such as data signals, sensed drive currents from the drive transistors, and predetermined voltages between display driver circuitry and the pixels. The switching transistors, emission transistors, and drive transistors may include semiconducting-oxide transistors and silicon transistors and may be n-channel transistors or p-channel transistors.

Abstract:

A system may include an electronic display panel having pixels, where each pixel may emit light based on a respective programming signal. The system may include a memory storing a map. The processing circuitry may determine a function for each pixel from the map. The processing circuitry may determine a respective control signal based on the function and a target brightness level for each pixel to generate multiple control signals, where the respective control signal is used to generate the respective programing signal for each pixel. The processing circuitry may determine a scaling factor based at least in part on the first map and may scale at least a subset of the multiple control signals based at least in part on the scaling factor.
