Abstract:

RF signal processing techniques based on orthogonal PN sequences can be implemented as passive circuits at the antenna to mitigate interference from co-site transmitters, multi-access interferers, or other blockers. Scaled CMOS transistors offer excellent RF switch performance as well as high frequency, low-power signal processing. We present a 45-nmCMOS SOI code selective filter that is capable of direct sequence spread-spectrum modulation and demodulation for full duplex or frequency duplex systems with high interference requirements.
