Unformatted text preview: 10/4/2004 Example A Diode Limiter.doc 1/7 Jim Stiles The Univ. of Kansas Dept. of EECS Example: A Diode Limiter Consider the following junction diode circuit: This circuit is a junction diode limiter ! Perhaps that would be clearer if we redrew this circuit as: This is the same circuit as above! 1K 1K v I +5V V ZK =10V v O open circuit 1K 1K v I 5V V ZK =10V v O + - +- + - 10/4/2004 Example A Diode Limiter.doc 2/7 Jim Stiles The Univ. of Kansas Dept. of EECS Now, lets determine the transfer function of this limiter. To do this, we must follow the 4 steps detailed in the previous handout! Step1: Assume junction diode is forward biased Replace the junction diode with a CVD model . ASSUME the ideal diode is forward biased, ENFORCE i D v = . We find that the output voltage is simply: 5 0 0 7 5 7 V O v . . . = + = while the ideal diode current is more difficult to determine. From KCL: 1 2 i D i i i = + where from Ohms Law: 1K 1K v I +5V - 0.7V + v O i D i i 1 i 2 10/4/2004 Example A Diode Limiter.doc Example A Diode Limiter....
