Latest Patents
Flink's latest patents include an improved differential amplifier designed to enhance the slew rate and provide a means for nulling the offset voltage during fabrication as an integrated circuit. This differential amplifier features an input stage connected to a current mirror, with a slew rate enhancement circuit that injects current into selected points of the circuit when the input voltage exceeds a predetermined threshold. Additionally, an offset trim circuit allows for the injection of a selected amount of current into the current mirror, effectively reducing the offset voltage.
Another patent involves a differential amplifier that includes a pair of input transistors connected to a first voltage potential through a first current source. This design allows for a selector network to inject a compensation current that compensates for mismatches in the input transistors. The balanced current mirror in this invention ensures that the output current remains substantially zero when the voltages at the input terminals are equal, thereby addressing the challenges posed by transistor mismatches.
