Abstract

Analog FIR filtering is proposed to improve the performance of a single stage g m -C channel selection filter for ultra low power Internet-of-Things receivers. The transconductor is implemented as a digital-to-analog converter; allowing a varying transconductance in time, which results in a very sharp FIR filter. The filter is manufactured in 22-nm FDSOI and has a core area of 0.09 mm 2 . It consumes 92 µW from a 700-mV supply and achieves f −60 dB/f −3 dB = 3.8. The filter has 31.5 dB gain, out-of-band OIP3 of 28 dBm and output referred 1-dB compression point of 3.7 dBm. The filter bandwidth is tunable from 0.06 to 3.4 MHz.
