3 Review Passive sign convention An ideal voltage/current source ALWAYS provides the same voltage/current. An independent source provides voltage/current independent of rest of the circuit. A dependent source provides voltage/current that depends on some voltage/current on the rest of the circuit.

4 Dependent Sources Output current or voltage is determined by other control voltages or currents Used to model gain Denoted by diamond shape + - 6 I b

5 Eg. Transistor Current flow is dependent on control signal (gate) Current changes based upon the value of the control signal (voltage between gate and source) Current (I) is therefore a function of the control signal No current from gate allowed (ideal) Source Control (Gate) Drain (lots of Electrons) V > 0 I
