  • Publication number: 20070126495
    Abstract: A circuit producing a reversed bandgap reference voltage circuit VRBG includes first and second resistors coupled as a voltage divider between ground and a first conductor, a base of a first transistor being coupled to the voltage divider to produce a first voltage VBE1(1+1/M) between the first conductor and ground, M being a ratio of the resistances of the first and second resistors. A third resistor is coupled between a base of the second transistor and ground to produce a second voltage VBE2+VRBGP between the second conductor and ground. First circuitry forces the collector current of the first transistor to be equal to the collector current of the second transistor, and second circuitry forces the first voltage VBE1(1+1/M) to be equal the second voltage VBE2+VRBGP. One of the first circuitry and second circuitry includes an operational amplifier coupled to effectuate the forcing.

  • Patent number: 6727752
    Abstract: A modulation scheme can drive an associated load that is coupled between a pair of outputs by providing a switching signal at one of the outputs and a non-switching signal at the other output independent of the direction of current relative to the respective outputs. Because switching occurs only at one of the outputs in this mode of operation, a single filter can be used to mitigate switching noise at the switching output. Another aspect relates to another mode of operation in which one or both of the outputs can be controlled to operate linearly, such as during a zero crossing condition, so as to help reduce crossover distortion.
