Floating Inductance Simulator with EXCCTAs
摘要
This paper introduces a floating inductance simulator with two extra X current conveyor transconductance amplifiers (EXCCTA) and three passive elements. The presented floating simulator (FS) has no passive component matching condition and operates at high frequency. The simulator employs one floating resistor and two grounded capacitors; the circuit is suitable for an integrated circuit (IC) platform. The presented FS has electronically tunable property due to having an inbuilt transconductance term (gm). The proposed FS is utilized in the tunable band rejection filter (BRF) and higher-order low-pass filter (LPF) application circuit for the workability test. All the simulation results are performed with 0.18 µm TSMC CMOS technology parameter with ±1.25 V. The theoretical approach is verified by computer simulation and experimental responses. The introduced FS is simple and utilizes two current-feedback operational amplifiers (CFOA) ICs (AD844) and one operational transconductance amplifier (OTA) ICs (LM13700) in the experimental arrangement.
