A 3rd-order current-mode filter in 0.12 μm CMOS

A 3rd-order current-mode filter in 0.12 μm CMOS

For software radio applications in system-on-chips, a 3rd-order current-mode Butterworth filter in 120 nm CMOS is realized. This filter is used for reconstruction purposes between a current-steering DAC and a current-mode mixer. Power can be reduced by using a current-mode architecture. The cut-off...
