A　continuous-time　low　pass　filter　(LPF)　for　high　bandwidth　application　is　presented　in　this　paper.　The　LPF　is　realized　with　6th　order　Chebyshev　structure.　Large　dynamic　range　is　achieved　by　adopting　linearity　enhanced　technique.　A　6-bit　controlled　switched-capacitor　array　is　realized　to　get　wide　programmable　cut-off　frequency.　The　measurement　results　indicate　that　the　-3　dB　cut-off　frequency　can　be　tuned　from　35　MHz　to　over　100　MHz.　The　two-tone　test　shows　that　the　in-band　IM3　can　achieve　-48　dB　with　500　mVp-p　input　swing.　This　proposed　filter　is　fabricated　in　TSMC　0.13　μm　CMOS　technology.　It　consumes　25　mA　current　with　3V　power　supply　and　occupies　0.5　mm2　area.　©2009　IEEE.
