Lastly, the realization of synthetic transformers using operational transconductance amplifiers and voltage differencing current conveyors demonstrates the flexibility of CDTAs in creating complex ...

We’re excluding anything made from discrete components, as well as less-general circuits like fixed-gain amplifiers and operational transconductance amplifiers (OTAs). Pinout of a TL084X2.

Where the Moon Phaser was based around a FET-driven circuit, offering 6-stage phase-shifting, the Solaria is driven by OTA ...
