摘要： A color palette selects a master clock from plural clock signals received at clock input terminals in response to a master clock selection control word received at control data terminals. A circuit forms a plurality of divided down clock signals from selected divide ratios of the master clock. A circuit selects a shift clock from among the divided down clock signals in response to at least some bits of an output clock selection control word received at the control data terminals. A circuit selectively enables and disables the shift clock in response to blanking data. A circuit selects a video clock from among the divided down clock signals in response to at least some bits of the output clock selection control word. A circuit synchronizes multiple bit words of color code received at color code input terminals with the master clock. A circuit outputs at least one memory recall address in response to receiving each multiple bit word of color code. A circuit stores color data words in a plurality of data storage locations, having associated memory recall addresses, and outputs a color data word upon receipt of an associated memory recall address. A circuit selectively writes color data words into these plural locations. A circuit synchronizes video control signals received at video control terminals with the master clock and provides the blanking data. A circuit selects for output between said color data words and true color data words received at said color code input terminals.

摘要： A MEMS may integrate movable MEMS parts, such as mechanical elements, flexible membranes, and sensors, with the low-cost device package, leaving the electronics and signal-processing parts in the integrated circuitry of the semiconductor chip. The package may be a leadframe-based plastic molded body having an opening through the thickness of the body. The movable part may be anchored in the body and extend at least partially across the opening. The chip may be flip-assembled to the leads to span across the foil, and may be separated from the foil by a gap. The leadframe may be a prefabricated piece part, or may be fabricated in a process flow with metal deposition on a sacrificial carrier and patterning of the metal layer. The resulting leadframe may be flat or may have an offset structure useful for stacked package-on-package devices.

A pair of current steering circuits (26, 28, 30, 32) are each connected in series with a respective one of the first and second current control devices (16, 18) for dividing respective currents in the first and second current control devices (16, 18) between a differential output current path (12, 14) and another current flow path, and a programmable voltage source (90) supplying V.sub.CONTROL is connected to control the current division by the current steering circuits (26, 28, 30, 32). The programmable voltage, V.sub.CONTROL, is provided by a programmable current control loop (90), which incorporates a master transconductance circuit, to establish a constant transconductance independently of temperature variations. A dynamically controllable resistance, such as an MOS transistor (24), or the like, is connected between the first and second current control input devices (16, 18), and a second voltage source (V.sub.GATE) is connected to the dynamically controllable resistance (24) to maintain the dynamically controllable resistance (24) at a constant value.

摘要： A biomedical sensor (20) is formed on a semiconductor substrate (22). Insulated dielectric layers (23, 24) are formed on the face and backside of the semiconductor substrate (22). Metal leads (26, 28) contact the substrate (22) through openings in the dielectric layer (23). The leads (26, 28) are also each connected to a set of interleaved longitudinal contact fingers (27, 29).
