    Ultra-low voltage, power efficient continuoustime filters in 180 nm CMOS technology
    (Institution of Engineering and Technology kvukmirovic@theiet.org, 2019) Rekha, S.; Vasantha, V.M.; Laxminidhi, T.
    The authors propose circuit techniques to implement integrated continuous-time filters for low voltage and low power applications. A fourth order Gm-C filter and a fifth order active-RC Chebyshev filter are used as test vehicles to validate the ideas. Basic building blocks are bulk driven transconductors. Gm-C filter and active-RC filter offer bandwidth of 1 MHz and 750 kHz, respectively while exhibiting a good figure of merit thus ensuring that the designs are energy efficient. Both the filters, fabricated on the same chip in 180 nm CMOS technology, operate on 0.5 V power supply. They offer a dynamic range of 45 and 46.6 dB, respectively. © The Institution of Engineering and Technology 2019.
