Cascode differential amplifier

Clean black line-art schematic of a symmetric CMOS cascode differential amplifier. Two lower MOSFETs form the differential input pair, with separate differential input gates. Above each input transistor is a cascode transistor, creating two tall vertical left and right branches. The upper side includes current-source load devices and additional cascode transistors stacked toward the supply rail, so the overall circuit appears as balanced transistor stacks between the top and bottom supply rails. Show a differential architecture with at least one clearly indicated output node on one side and the corresponding opposite-side output node implied or shown, using standard MOSFET schematic symbols and a neat symmetric layout.
