WIDEBAND LNA WITH OUTPUT MATCH CONFIGURABILITY

This abstract first appeared for US patent application 18335549 titled 'WIDEBAND LNA WITH OUTPUT MATCH CONFIGURABILITY

Original Abstract Submitted

Methods and devices to mitigate the detrimental effects of highly capacitive output routes of multiple gain low noise amplifiers on the overall performance of the circuit are disclosed. The disclosed methods and devices implement the same inductive element across the output load in both the low gain and high gain operational modes. Furthermore, such devices implement switches to control the selection of different signal paths for the high gain and low gain mode. The implemented switches are also used to selectively adjust the isolation of the output stage of the LNA.
