Abstract
Wireless local area network is widely used in industry and people daily life. More and more mobile devices rely on this technology to perform data communication with 2.4 GHz and 5 GHz frequency band. As the development of CMOS technology is able to keep shrinking chip size and increasing circuit integration density, traditional on-chip passive inductor inefficient area consumption issue is becoming critical to receiver front end system design. In this dissertation, an active inductor-based band pass filter is studied and implemented with 90 nm technology. This active inductor design provides very small area consumption and larger quality factor compared to conventional passive circuit. Moreover, to overcome the process variation issue on active circuit during fabrication, an automatic calibration system is implemented to monitor and compensate the process variation error of band pass filter center frequency at post-fabrication phase. Also, an 802.11ac standard receiver is designed in this dissertation with active filter and Hartley image rejection architecture embedded into the system. The receiver can down-convert a 5.25 GHz signal to a 250 MHz IF signal with input power from -90 dBm to -50 dBm. The area consumption of entire receiver is expected to be smaller compared to other published works.
