About the article

1 kH Synthetic Inductor

Inductors can be mimicked quite easily using operational amplifiers. The circuit shown here was developed to have an inductance of 1000 H (say, one thousand henry) with good damping. Using this design you can build a resonant circuit with a centre frequency of less than 1 Hz. The slow behaviour allows you to use conventional measuring instruments to investigate the circuit in real time. The circuit can also be used as part of a filter design.
