  • System and method for soft-starting a power converter with a pre-charged output
    Patent number: 8890501
    Abstract: A method for soft-starting a voltage generator includes disabling an output driver; detecting the voltage on an output node; ramping a reference voltage at a controlled rate from a predetermined first level until the reference voltage reaches a second level that is a predetermined function of said output node voltage; enabling the output driver when the reference voltage reaches said second level; and then ramping the reference voltage and the output node voltage at a controlled rate to a boot voltage level. A soft-start circuit for an output voltage generator includes a comparator for causing a ramp generator to ramp the reference voltage and the voltage on the output node to a boot voltage level at a controlled rate once the comparator detects that the reference voltage is substantially equal to the voltage on the output node.

  • True/complementer for a half-band filter
    Patent number: 5574671
    Abstract: A digital half-band filter with mutliplications using Wallace trees which have lower bits truncated for reduction in size and with a true/complementer providing saturation compensation together with accumulator overflow compensation by monitoring bits more significant than the output bits.
