Low-frequency, continuous-time notch filter using G sub(m)-C circuits

A 60 Hz notch filter that can be integrated on a chip is reported. G sub(m)-C filters are used for the necessary time constant multiplication. This filter can easily be tuned and is relatively insensitive to temperature variation. The notch depth can reach 60 dB.
