Optimized Design of OTA-Based Gyrator Realizing Fractional-Order Inductance Simulator: A Comprehensive Analysis

“…Input resistance is usually very large, especially in CMOS technology; whereas, input capacitance is typically in the range of tens to the low hundreds of femtofarads when integrated on a substrate of standard CMOS processes. The output resistance of OTA generally reaches several hundreds of kiloohms and output capacitance tens to a few hundreds of femtofarads [24,25]. For some OTA implementations, the parasitic properties may be dependent on the OTA operating conditions, e.g., the terminal conductance may change depending on the set transconductance, which is also the case of the amplifier used in the computer simulation example in this article.…”

Design and Realization of Broadband Active Inductor Based Band Pass Filter

“…One of the frequently addressed method in high performance filtering systems is the usage of tunable filters. Most of tunable band-pass filter designs usually use spiral inductors with the performance limitations including low Q factor, low inductance value without tuning capability, small self-resonance frequency and high silicon surface area [1]- [3]. One of the efficient solutions for the mentioned challenges is the realization of the active inductor (AIN), which has become a promising solution with the advantages to be listed as wide range of operation frequency and tuning capabilities for multistandard systems [4]- [6].…”
