Method and system for an analog crossbar architecture

摘要

Methods and systems for an analog crossbar may comprise, in a wireless device comprising a receiver path with an analog crossbar: receiving a digital signal comprising a plurality of channels; amplifying the received signal; converting the amplified signal to an analog signal; separating the analog signal into a plurality of separate channels; routing the plurality of separate channels to desired signal paths utilizing the analog crossbar; and converting the routed plurality of separate channels to a plurality of digital signals. The analog crossbar may comprise an array of complementary metal-oxide semiconductor (CMOS) transistors. The analog crossbar may comprise a plurality of differential pair signal lines, and a plurality of single-ended signal lines. The received signal may be amplified utilizing a low-noise amplifier (LNA), where a gain level of the LNA may be configurable. The analog signal may be separated into separate channels using a channelizer.
