9/2/2011 2 Where are the applications? Analog circuits vs Digital circuits A Radio Frequency tuner (RF) B Digital Signal Processing units (DSP) C Microcontroller D CPU 5 Schedule 6 Given : complex system of sources & resistances, output @ terminals a-b Intuition Theorem : Can replace with circuit of 1 source & 1 resistance. Voltage source in series with equivalent resistance Current source in parallel with equivalent resistance a b a b Equivalents: Look in to terminals a & b, ‘’see’’ same output & behavior Thevenin Equivalent Circuit Find: 1) Open-Circuit Voltage (v oc ) 2) Short-Circuit Current (i sc ) 3) Thevenin Resistance: R t = v oc /i sc V t v oc R t v oc i sc
