Abstract: This paper analyses the effect of finite gain-bandwidth of the operational transconductance amplifiers (OTAs) on active-RC integrators. A feed-forward compensated OTA is taken as the building block of active-RC integrator. A mathematical analysis is carried out on a first order low-pass active-RC filter designed in 180 nm CMOS technology to operate at a supply voltage of 0.5 V. A non-ideality factor (NIF) has been defined that accounts for the deviation of the response from the ideal. Simulations performed on the transistor level filter justifies the mathematical analysis presented. � 2012 IEEE.
