A method of arranging components in an integrated circuit includes providing two or more circuit cells of a first type and providing two or more circuit cells of a second type. The circuit cells of the first type are configured to operate in conjunction with the circuit cells of the second type. The method further includes arranging the circuit cells of the first and second types in an alternating pattern such that each circuit cell of the first type is adjacent to at least one circuit cell of the second type. The alternating pattern may be an array of rows and columns and may include a repeating pattern of one first type cell and one second type cell in each of the columns. The alternating pattern may include a repeating pattern of one cell of the first type and two cells of the second type in each of the columns.

Voltage reference and current source mixing method for video DAC

A method of driving a pixel array includes providing a ramp signal to one or more columns of the pixel array. For each cycle of the ramp signal, the method further includes providing a first row driving signal to at least a first row of the pixel array and a second row driving signal to a second row of the pixel array. A pixel array driver may include a ramp signal generator configured to produce a ramp signal, a first amplifier configured to receive the ramp signal and produce a first amplified ramp signal, and a second amplifier configured to receive the ramp signal and produce a second amplified ramp signal. The first amplified ramp signal may be electrically connected to a first set of pixels of a pixel array, and the second amplified ramp signal may be electrically connected to a second set of pixels of the pixel array.

Two rows driving method for micro display device

The invention is a multi-microphone voice processing SoC primarily for head worn applications. It bypasses the use of conventional pre-amp voice CODEC (ADC/DAC) chips all together by replacing their functionality with digital MEMS microphone(s) and digital speaker driver (DSD). Functionality necessary for speech recognition such as noise/echo cancellation, speech compression, speech feature extraction and lossless speech transmission are also integrated into the SoC. One embodiment is a noise cancellation chip for wired, battery powered headsets and earphones, as smart-phone accessory. Another embodiment is as a wireless Bluetooth noise cancellation companion chip. The invention can be used in headwear, eyewear glass, mobile wearable computing, heavy duty military, aviation and industrial headsets and other speech recognition applications in noisy environments.

Digital voice processing method and system for headset computer

A method of generating column signals for use by a pixel array includes connecting two or more controllable bus buffers in series. The output of each of the two or more controllable bus buffers drives an associated node. The method further includes providing a column data signal to an input of the series-connected string of two or more controllable bus buffers. The method also includes sequentially enabling each controllable bus buffer in the series-connected string of two or more controllable bus buffers, such that each node is sequentially driven. Each node is electrically coupled to an input of an associated controllable local output buffer. The method further includes sequentially enabling each of the controllable local output buffers in an order associated with the sequentially enabling of the controllable bus buffers.

Column bus driving method for micro display device

A unit pixel driver circuit includes a capacitor configured to store a voltage corresponding to a desired pixel brightness and a control block. The control block may include a first, second third and fourth transistors, all of which are connected together, both in parallel and in series. The control block controls, based on the voltage stored in the capacitor, the amount of current flowing through a pixel LED. The first transistor, second transistor, third transistor and fourth transistor all share a common gate geometry size.
