Bjt cascode amplifier resistive load

Clean textbook schematic of a bipolar cascode amplifier with two vertically stacked NPN transistors, shown as a lower device and an upper device connected in cascade. The lower transistor base is the signal input, the upper transistor base is tied to a bias reference, and the collector-emitter path is aligned vertically with the collector of the lower transistor connected to the emitter of the upper transistor. The output node is at the collector of the top transistor, with a load resistor connected above it. Standard transistor symbols, thin black wiring, and compact black-and-white schematic presentation.
