The paper presents a synthesis procedure for realizing RC active filters using nonzero finite gain amplifiers. It is shown that the pole sensitivity of the transfer function can be minimized by RC-RL decomposition.doi:10.1080/00207217508920393
Ideally, the stopband must be flat but has ripples in practical as in Fig. 2–4. Therefore various mathematical approximation functions are used to design best suited transfer functions for linear analog filters. The most commonly used function is the low-pass Butterworth Filter design. The filter...

A new synthesis procedure is formulated for RC-active filters. It involves the use of idealized unity-gain current and voltage amplifiers as the active clement. To realize a pair of complex conjugate poles we can use either a unity-gain current amplifier with appropriate RC-feedback and input ...

The time associated with the charge-trapping and de-trapping mechanisms are incorporated by using RC filters on the input-stress voltage functions which are then fed into the threshold voltage calculation of access regions transistors. The current-collapse phenomenon is empirically known to scale-up ...
Finite gain compensated double-sampled switched-capacitor integrators for high-Q bandpass filters A technique for the compensation of the operational amplifier (op-amp) finite gain error in the switched-capacitor (SC) integrator is proposed. Two possibl... Baschirotto A.,Castello R. - 《IEEE Tr...
Recall that the function of the low-pass RC filter in the demodulating circuit was to stop the 455 kHz carrier frequencies but to pass the audio frequencies. The RC filter time-averages out the carrier variations but not the audio variations. Now, if we could also time-average out the ...
