Cascode current mirror

A compact four-transistor MOSFET cascode current mirror schematic drawn in clean black textbook line art. The circuit is arranged as two symmetrical vertical branches, each branch containing two stacked transistors: a lower mirror device and an upper cascode device. One branch is diode-connected with gate and drain tied to form the reference side, while the opposite branch provides the mirrored output current. Shared gate-bias interconnections run across the corresponding transistors in both branches. Use standard analog circuit-symbol geometry, clear vertical stacking to emphasize the taller cascoded structure, a reference-current input on the left branch, and an output node on the right branch.
