The paper reviews earlier works on active RC integrators and their compensation schemes. Some works suggesting enhancement and lowering of integrator and differentiator time constants have also been considered. Some new 2-OA schemes have then been proposed which use one capacitor, either floating or ...
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-...

An active RC integrator filter with finite operational amplifier bandwidth can be compensated by biasing the operational amplifier input stage such that its transconductance becomes a function of the resistance. Thereafter, by inserting another resistance of the same material in series with the integrating...
An autonomous passive–active integrators oscillator with anti-parallel diodes is proposed and analysed in this paper. It consists of anti-parallel diodes and two main blocks: A second-order passive RLC integrator and a first-order active RC integrator. The existence of two Hopf bifurcations is es...
A synthesis procedure for the realization of a general voltage transfer function without real axis zeros using a single fixed gain amplifier, an one-port and one RC two-port has been presented. The merits of the circuit compared to other active RC synthesis procedures using a single fixed gain...
Through the use of signal flow graph concepts, known ladder simulating active networks as well as new ones can be obtained. An example of an all integrator canonic active bandpass ladder is also given.doi:10.1080/00207217908938665HAB-ITANTISI....
Finally, an 8order Butterworth active Biquadrate RC filter has been designed and this OTA was checked by a typical switched-capacitor (SC) integrator with a 1 MHz clock-frequency. 展开 关键词: Operational Transconductance Amplifier (OTA) Common-Mode Feedback (CMFB) Bulk-Input Switched-Capacitor ...
摘要原文 The noise limitations of some important low-sensitivity RC-active filter realizations are derived; the inherent rms noise (noise from essential network resistors) that exists at the output terminals of a bandpass active filter is determined for two-integrator loop and positive impedance conver...
