Abstract :
A new architecture is presented for a sinc2(f) filter intended to sample channels of varying bandwidth when surrounded by blockers and adjacent bands. Sample rate is programmable from 5 to 40 MHz, and aliases are suppressed by 45 dB or more. The 0.13-mum CMOS circuit consumes 6mA from 1.2V
