High frequency equivalent circuit

A compact textbook-style small-signal high-frequency transistor equivalent circuit drawn as a clean black schematic with thin line-art and minimal labels. The diagram shows one input terminal and one output terminal separated around a transistor small-signal model. Include an input resistor, a base-emitter or gate-source resistance, a controlled dependent current source, and an output resistance. Add two parasitic capacitances connected around the transistor nodes, such as base-emitter and base-collector or gate-source and gate-drain capacitors. Include a ground reference, standard resistor and capacitor symbols, neatly arranged signal nodes, and a clear simplified high-frequency equivalent layout.
