The gyrator, or electronic
inductor, is based on a
Type NE5532 operational amplifier
and can be used in filters
and other apphcauons at
frequencies of up to 1 kHz.
The circuit is particularly useful
for applications where large
values of self inductance are
requtred. It is not good destgn
practice to use a gyrator of
onlya fewrnH, butwtndmg an
inductor of, say, 100 mH is a
sufftctently cumbersome task
to use a gyrator instead. The
present circuit can simulate
inductances of 1 mH to well
over 100 H.
