  • Abstract
    A CMOS polyphase low-IF filter with on-chip frequency control for a 2.4 GHz wireless LAN is presented. Designed in a 1.8 V, 0.18 mum standard CMOS process, this Chebyshev polyphase filter has a 7th order 0.5 dB passband ripple. An on-chip auto frequency control module is designed for the variation of process in order to get the required sensitivity of the filter. This filter consumes 1.74 mW including the on-chip control module and the total chip area is 0.276 mm2.
