Yep. That topology is called a gyrator. Often used in IC's where it is hard to make an inductor.

- kazinator 3mo agoI spotted a fixed equalizer in the middle of a guitar power amp schematic (Randall G3 series), so I banged it up in LTSpice for a simulation: https://www.ssguitar.com/index.php?topic=5751.msg45172 https://www.ssguitar.com/index.php?topic=5751.msg45172 I came up with a nice schematic layout whereby we have the gyrators in a column on the right and then the mixer resistors which plug them into the fixed equalizer to the right, making it easier to follow.
