Two novel and generalised schemes are given for the realisation of grounded and floating immittance simulators. The use of operational transconductance amplifiers (OTAs) lends wide range electronic tunability to the schemes. The first scheme is particularly used in the realisation of new all active device ideal grounded inductance and super inductance simulators. These circuits employ only an OTA along with an operational amplifier (OA) modelled in its first pole roll-off characterisation. Similarly, the second scheme is used in realising novel ideal floating inductance and super inductance simulators. The all active device floating simulators only require a simple matching constraint to be satisfied in its realisation. Both the circuits use only active devices and have wide range linear electronic tunability and reliable high frequency performance. The effects of non-ideality of the OAs on the circuit performance is also examined. The simulators are highly suitable for monolithic implementation in either...read more
