“…The commonly used CMFB circuit using differential pairs [13] is not adequate in this application because the large differential swing at the output can completely turn off one input transistor and cause non-linearity. The proposed CMFB circuit uses a structure similar to the DM path and therefore offers comparable linearity.…”

A tunable Gm-C filter is presented for bio-signal acquisition application. It incorporates linear tunable transconductors utilizing MOSFETs biased in the triode region. Both the filter architecture and transconductor circuit design are optimized for good tuning, linearity and noise performance with low power consumption. The filter was fabricated in a 0.6 μm BiCMOS process, occupying 0.17 mm 2 . Measurement results show a tuning range of cut-off frequency from 2.5 kHz to 10 kHz. At 5 kHz cut-off frequency, the filter achieves a dynamic range of 85 dB with 1% THD, and consumes 75.9 μW from 3.3 V supply.

We present a low-voltage low-power CMOS tunable transconductor exploiting body gain boosting to increase the small-signal output resistance. As a distinctive feature, the proposed scheme allows the OTA transconductance to be tuned via the current biasing the gain-boosting circuit. The proposed transconductor has been designed in a 0.13-µm CMOS technology and powered from a 1.2-V supply. To show a possible application, a 0.5-MHz tunable third order Chebyshev low pass filter suitable for the Ultra Low Power Bluetooth Standard has been designed. The filter simulations show that all the requirements of the chosen standard are met, with good performance in terms of linearity, noise and power consumption.
