Folded cascode amplifier single input

Compact transistor-level CMOS folded-cascode amplifier schematic in clean black line art on a white background. Show one input transistor as a lower common-source device receiving input vi, with its current folded into an opposite-polarity common-gate or cascode branch above rather than being directly stacked. Include an upper MOS transistor with gate bias labeled VG2, a top supply rail labeled VDD, a single-ended output node labeled vo on one side, and separate bias or current-source branches. Use standard MOSFET symbols with clearly drawn gate, drain, and source terminals, arranged in a compact analog integrated-circuit style that emphasizes the folded current path.
