Folded cascode stage

Schematic-style folded-cascode amplifier stage drawn in clean black lines on a white background, using standard bipolar transistor symbols. Show a neat, symmetric analog-IC textbook arrangement with an input differential pair feeding vertically stacked cascode transistors. The signal currents are redirected through intermediate folding nodes into opposite-side or upper branches, creating the characteristic folded current paths. Include multiple stacked BJTs, balanced mirrored left-right structure, and differential output taken between two high-impedance collector nodes. The overall subcircuit should appear compact, dense but orderly, with collector and emitter terminals arranged to emphasize the cascoded vertical current path and the sideways folding of branches.
