A generalized structure that is capable of implementing power-law filters derived from 1st and 2nd-order mother filter functions presented in this work. This achieved thanks to the employment Operational Transconductance Amplifiers (OTAs) as active elements, because electronic tuning capability their transconductance parameter. Appropriate design examples are provided performance introduced evaluated through simulation results using Cadence Integrated Circuits (IC) suite Metal Oxide Semiconductor (MOS) transistors models available Austria Mikro Systeme (AMS) 0.35 μm Complementary (CMOS) process.
