Latest Patents

Among his latest patents, one is titled "Techniques for determining inductances." This invention involves a circuit system that includes a current sensor circuit, a subtractor circuit, a multiplier circuit, and a divider circuit. The current sensor circuit generates a current sense signal that indicates a current through an inductor. The circuit system generates a current value based on the current sense signal. The subtractor circuit determines a voltage difference across the inductor. The multiplier circuit multiplies the voltage difference by a time period that the voltage difference is applied across the inductor to generate a product. The divider circuit divides the product by the current value to generate an estimated inductance of the inductor.

Another significant patent is the "Integrated current replicator and method of operating the same." This integrated current replicator includes a first current sense resistor configured to sense a first input current to a power converter during a primary portion of a duty cycle and a first transconductance amplifier configured to produce a first voltage at a common circuit node proportional to the first input current during the primary portion of the duty cycle. Additionally, it includes a second current sense resistor configured to sense a second input current to the power converter during a complementary portion of the duty cycle and a second transconductance amplifier configured to produce a second voltage at the common circuit node proportional to the second input current during the complementary portion of the duty cycle. The integrated current replicator also includes an amplifier configured to produce a voltage replicating the first input current and the second input current from the first voltage and the second voltage.
