摘要： A voltage regulator circuit is disclosed. The voltage regulator includes a feedback circuit configured to generate a feedback signal based on a voltage level present on a regulated power supply node. A comparison circuit is arranged to generate an error signal based on the feedback signal and a reference voltage level. A compensation circuit is configured to modify the error signal, based on a routing impedance coupled between the regulated supply voltage node and a load circuit, to generate a control circuit. An output circuit of the voltage regulator is configured to source current to the regulated power supply node based on the control signal.

摘要： An electronic display may include a pixel circuit. The pixel circuit may include memory storage to store data values representative of image data to be depicted via the pixel circuit. The memory storage may also include memory components for storing bits of the data value. The pixel circuit may also include a light-emitting device for emitting light based at least in part on the data value and a controller. The controller may receive the data value and store the bits based on a mapping between the bits and the memory components. The mapping may be determined based on routing one or more of the bits associated with one or more defective memory components of the memory components to one or more other memory components of the memory components. The controller may also drive the light-emitting device to emit light based on the bits stored in accordance with the mapping.

摘要： In some examples, a touch screen can include touch electrodes that can function as drive (Tx) electrodes and sense (Rx) electrodes during a touch sensing operation of the electronic device. The drive electrodes can include +Tx electrodes and −Tx electrodes that can receive drive signals that can have the same amplitude and frequency and opposite phases, for example. In some examples, the surface areas of the +Tx electrodes and the −Tx electrodes can be the same and the distances of the +Tx electrodes and −Tx electrodes from the Rx electrodes can be different. In some examples, the total charge coupled to a proximate or touching object can be zero, which can mitigate problems associated with ungrounded or poorly grounded objects in contact with the touch screen.

摘要： A bias current circuit is disclosed. The bias current circuit includes a number of current sources that can selectively be coupled to a bias current node or an auxiliary node. The bias current may be provided through the bias current node. During a trimming operation, a control circuit may selectively couple particular ones of the current sources to the bias current node, in accordance with a desired bias current. Other ones of the current sources may be coupled to the auxiliary node, through which an auxiliary current is provided. Upon completing the trimming operation, the control circuit may cause the auxiliary current to be reduced to zero.
