Current source in small signal model
WebThe small signal model is dependent on the DC bias currents and voltages in the circuit (the Q point). Changing the bias moves the operating point up or down on the curves, … WebSmall-Signal Model + v m - gv r o i It is imperative that you understand that the circuit to my right is the small-signal equivalent circuit for an ... current source model is therefore: Ideally, r o =∞. However, for good current sources, this output resistance is large (e.g., rK o =100 Ω). Thus, we mostly
