Abstract

A traditional approach of simulating floating inductance in active gyrator of OTA of equal transconductance is successively used in obtaining LC ladder consisting of four stages .The calculations done on floating inductance evaluate the respective cut off frequencies as expected from the calculation of resonant frequency. The equal transconductance of gyrators is more advantageous in the low pass filter design. A unified approach of gyrator LC filter with floating inductor is successively used for studying the response. This has the property of reducing noises at high frequency signal processing applications. The response of four stage ladder using discrete components is presented. From the comparison it is possible to bring out the salient features of ungrounded inductance simulations using two gyrators at a time. In the circuit arrangement the simulation of two grounded inductance of equal transconductance are used to obtain a single floating inductor.
