Electronic Devices Having Complementary Current Mirror Circuitry - A simplified explanation of the abstract
This abstract first appeared for US patent application 17734642 titled 'Electronic Devices Having Complementary Current Mirror Circuitry
Simplified Explanation
- The patent application describes an electronic device that includes wireless circuitry with various components such as digital-to-analog converters, filters, mixers, and current buffers. - The current buffers are responsible for providing the correct resistance termination for the filters. - These current buffers consist of current mirrors made up of diode-connected n-type transistors and diode-connected p-type transistors. - The current mirrors collectively offer a linear input resistance. - The current mirrors receive a high voltage from a voltage regulator that includes a replica current mirror and proportional-to-absolute-temperature current sources.
Original Abstract Submitted
An electronic device may include wireless circuitry having digital-to-analog converters, filters, mixers, and current buffers disposed between the filters and the mixers. The current buffers may provide proper resistance termination for the filters. The current buffers may include current mirrors formed from diode-connected n-type transistors and diode-connected p-type transistors, which collectively provide a linear input resistance. The current mirrors may receive a high voltage from a voltage regulator having a replica current mirror and proportional-to-absolute-temperature current sources.
