A 1-V 2-mW Active-RC Low-Pass Filter With Programmable Cutoff Frequency in 22 nm CMOS

A 5th-order Chebyshev-I active-RC analog low-pass filter (LPF) with programmable cutoff frequency (f0) was fabricated in a 22nm ultra-low-leakage CMOS process. The proposed filter is targeted to application scenarios such as low-voltage and low-power wireless communication systems with different base-band signal bandwidths. The cutoff frequency reconfiguration of the filter is realized ...
