The core of the design is formed around a low noise JFET in a folded cascode circuit. JFET J1 and pnp transistor Q3 together form a folded cascode amplifier. Transistors Q1 and Q2 are configured as a ...

This dependence allows the amplifier to have a larger output swing than that of a classic folded cascode. The target specifications for the amplifier circuit make the design challenging in both 0.18- ...

[2] A fully-differential improved recycling folded-cascode amplifier for fast-settling switched-capacitor applications. Engineering Science and Technology an International Journal (2024).

It relies on design knowledge extraction, which renders it very fast compared to full optimization approaches and allows handling of much larger circuits. This technique studies the original design ...
