A 33 MHz 70 dB-SNR Super-Source-Follower-Based Low-Pass Analog Filter
No full textIn this paper, a 4th-order low-pass continuous-time
analog filter is presented, that is implemented with the cascade
of two efficient and compact biquadratic cells, realized using the
Super-Source-Follower topology. The biquadratic cell uses only
two capacitors and four transistors: two transistors for the signal
processing and two transistors as current sources for biasing pur-
pose. The 4th-order filter prototype has been integrated in 0.18 μm
CMOS technology. For a 33 MHz cut-off frequency, the filter per-
forms 18 dBm-IIP3 for two tones at 2 MHz and 3 MHz, with total
current of 770 μA from a single 1.8 V supply voltage
