Abstract :
A novel ideal grounded inductance simulator (GIS) is realised using an operational transconductance amplifier as the active device. This simulator uses a low component count and has no matching constraint in its implementation. It is linearly tunable over four decades using bias current or voltage control. The circuit has attractive sensitivity characteristics and reliable high-frequency performance. The effect of nonideal buffers on the performance is studied. A floating inductance simulator, with identical properties, may be realised directly through an appropriate interconnection of two GISs. Experimental results are found to support the theory
