Abstract
For the analog baseband section of a 60GHz receiver for fast download applications, two 5th order Butterworth filters with cutoff frequency of 880MHz and 1.76GHz for 60GHz radios are implemented in 40nm low power digital CMOS, using Sallen and Key biquads. Drawing 25/21mA from a 1.1V supply, an IIP3 of -13/-12dBV to -16.7/-18.3dBV and an input-referred noise of 320/280μVrms are measured for the 880/1760MHz filter.Keywords
