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.
