Abstract :
A 3/sup rd/-order Chebyshev bandpass filter, that employs on-chip passive elements with Q-enhancement technique, achieves an insertion loss of 0 dB and a passband of 60 MHz around a center frequency of 2140 MHz. Fabricated in a 0.25-/spl mu/m CMOS, the filter operates with 2.5-V supply and 7 mA. The filter occupies an area of 1.3 mm /spl times/2.7 mm.
