摘要： A receiver front end capable of receiving and processing intraband non-contiguous carrier aggregate (CA) signals using multiple low noise amplifiers (LNAs) is disclosed herein. A cascode having a “common source” input stage and a “common gate” output stage can be turned on or off using the gate of the output stage. A first switch is provided that allows a connection to be either established or broken between the source terminal of the input stage of each cascode. Further switches used for switching degeneration inductors, gate/sources caps and gate to ground caps for each legs can be used to further improve the matching performance of the invention.

摘要： A charge transimpedance amplifier (CTIA) input cell includes a high gain capacitor configured to integrate charge arising from photocurrent, a low gain capacitor, and a switching element that can switch the low gain capacitor to be electrically coupled in parallel to the high gain capacitor. In some examples, the switching element is a low gain switch, which can be manually activated to switch in the low gain capacitor. In these examples, the low gain switch can be electrically disposed between the low gain capacitor and a source of the photocurrent. In other examples, the switching element is a low gain transistor, which can be automatically activated to switch in the low gain capacitor when a voltage across the high gain capacitor reaches a specified threshold. In these examples, the low gain capacitor can be electrically disposed between the low gain transistor and the source of the photocurrent.
