A 0.8V CMOS filter based on a novel low voltage operational transresistance amplifier. Ravindran, A., Savla, A., Younus, M., & Ismail, M. In Midwest Symposium on Circuits and Systems, volume 3, 2002.
abstract   bibtex   
Operational transresistance amplifier (OTRA) is suited for low voltage operation since it minimizes stacking of transistors due to the use of shunt-shunt feedback topology. A second order low pass filter with independent tuning of DC gain, cutoff frequency and Q factor was designed based on the Tow-Thomas biquad, using a novel low voltage OTRA in 0.18μ CMOS technology. The filter operates at a supply of 0.8V, has a 3dB cutoff of 600KHz, VIP3 of 2.85V, input referred spot noise at 1KHz of 115nV/√Hz and consumes 0.7mW power.
