Latest Patents

One of Cooper's latest patents is titled "GTL output structure having a slew rate control restore circuit." This invention features an active charging and discharging stage that restores internal nodes for slew rate control without relying on slow rise and fall RC time constants. The innovative GTL output structure includes an input stage connected to an RC network for providing slew rate control, along with an output stage that connects between the RC network and a feedback network. The feedback network comprises an active charging stage that supplies a charging current to the gate of at least one transistor, as well as an active discharging stage that provides a discharge current from the gate to ground.

Another significant patent is the "Quasi-complementary BiCMOS circuit with enhanced pull down transistor." This circuit includes a clamp circuit that automatically discharges the base-collector of a pull down bipolar transistor when the collector voltage equals the base voltage. The immediate action of the clamp circuit does not depend on feedback circuit performance, allowing for quick discharge of shallow saturation after the pull down transition. The degree of shallow saturation can be controlled by selecting the size of the clamp transistor.
