At ON Semiconductor, we offer two types of precision operational amplifiers, NCS21911 & NCV21911, which are excellent choices that meet the requirements of exact performance over a broad temperature range (-40oC to 125oC) and maintains this performance over the many years of operation required by the industrial market.
This way is preferred in the design of a lot of VM fractional order filters where active building blocks of operational amplifiers (OPAMPs), CCs, current feedback operational amplifiers (CFOAs) etc.

The proposed structure is simulated and implemented using AD844 current conveyors and LF353 wideband operational amplifiers. According to the measurements and simulations the proposed instrumentation amplifier is superior in CMRR compared to the previous current conveyor based implementations.
This amplification process is accomplished using bio-amplifiers such as operational amplifiers basically instrumentation amplifier.
The end stage operational amplifier is a two-stage PMOS class-AB output buffer with a 0.2 V to 4.8 V output voltages.
The substrate P3 has two contact areas; one of them is connected to the system's earth, and the other is connected to the data collection board (DCB) through INA128 operational amplifier installed within the vacuum chamber beside the substrate.
Hence the drain, source and reference gate from a mini model glass electrode are connected with the operational amplifier. The OPA4277 operational amplifier is used for amplification since it is highly stabilized with internal temperature compensation and ultra low offset voltage.
For instance, the authors in [7] have already implemented Chua's circuit to generate multiscroll chaotic attractors by using commercially available current-feedback operational amplifiers (CFOAs).
