Explicit transfer function of RC polyphase filter for wireless transceiver analog front-end
Proceedings. IEEE Asia-Pacific Conference on ASIC, - Trang 137-140
Tóm tắt
This paper derives explicit frequency transfer functions for first-, second- and third-order RC polyphase filters (which are important components in analog front-end of wireless transceivers for I, Q signal generation and image rejection) using a concept of complex signal and circulant matrix properties. The results allow us to exploit their characteristics systematically.
