    摘要： Driver circuit that generates an output drive signal that can be used to drive a light source (e.g., a light emitting diode (LED)) is described. The driver circuit includes an output transistor that operates in either a saturation region or a triode region. The driver circuit employs feedback to generate an output drive signal (e.g., an output drive current) that is independent on the operating mode of the output transistor.

    摘要： A driver circuit for driving a light source of an optical pointing device includes a first transistor coupled to the light source. The driver circuit includes a controller coupled to the first transistor for monitoring a first current through the light source, comparing the first current to a reference current, and generating a control signal based on a result of the comparison, wherein the control signal causes the first transistor to change the first current.

    摘要： An integrated circuit cast on a single die having a plurality of receivers in a receiver region, a plurality of transmitters in a transmitter region, and a spatial separation region having a plurality of n-type and p-type subregions disposed on the single die to separate the transmitter region from the receiver region. The pn-junctions between the n-type and p-type subregions are reverse-biased thereby reducing or eliminating coupling of noise and crosstalk between the transmitter and receiver is reduced.
