A 100MHz CMOS gm-C bandpass filter

Summary, in English

has a center frequency of 100MHz and a passband of 10MHz. The filter architecture is insensitive to parasitic capacitances, which allows for the implementation of bandpass filters over a very large frequency range. Intrinsic parasitic Q-enhancement techniques have been used, thus, obviating the need for any additional Q-tuning circuitry. The presented filter has small implementation losses with characteristics suitable for a first IF filter of a wideband system like a WLAN (e.g. DS-CDMA 802.11).
