A charge-domain downconversion sampling mixer with an embedded four-path bandpass filter for band selection and a sinc 3 finite impulse response (FIR) and a first-order sinc FIR with a decimation of 4 for channel selection is proposed to provide sufficient attenuation of outof-band blockers and aliasing interferences. The sampling mixer designed in an IBM 130 nm 1.2 V CMOS with a 100 MHz input exhibits an 80 dB suppression of aliasing interferences and a 57 dB stopband attenuation while consuming 1.08 mA.
