Diodes in the circuit shown in attached figure are assumed to have a constant 0.7 drop across them when they conduct. The op-amp is ideal. Its saturation limit is +/- 12V

a) Sketch the transfer characteristic vo vs vi.

b) What is the maximum diode current?

Sketch the voltage transfer characteristics of the attached circuit [ i.e. Vo vs Vi ]

[ input trigger and Threshold are tied together with an input voltage Vi]

common sajhaites... help me out here (O:

==================================================
this time
i really do not know them )O:

Let me know if you have an answer. I have the same problem in my homework due next week.

yup acharya jyu,
after 24 hrs.. finally i got to it. (O:

so what u paying for it (O:

=====================================================
this time i found the answer

btw, if u r really serious about the answer send me email. I will send u the answer.

थापा जीलाई हेल्लो भन्न मात्र पसेको, अस्ति मेरो समस्या समाधान गरिदिएकोले :-)

मेरो दिमागमा त अझै पनि त्यो अबरोधक (Resister) को अगाडि र पछाडि कसरी उही
बिजुली बग्न सक्छ भनेर घुमिरहन्छ। ५ एम्पियर पसे पछि अबरोधकले खाएर २-४ एम्पियर मात्र बाहिर आउनु पर्ने जस्तो लाग्छ, अझै। :-)

गुल्टिँदै गरम्.....

see this you might some some clue . positive feedback opamp config .

max diode current is gonna be
(12-0.7)/(10k) - (0.7-0)/(60+10)k
=11.63/10k - (0.7/70k)
=1.163mA - 0.01mA
=1.153mA

1st one is an example of Schmitt Trigger. So the x-fer characteristic will be that of Schmitt trigger with kind of hysteresis effect. And the 2nd one is a detailed diagram of 555 timer. So bro X-fer characteristic will be that of 555 timer with monostable vibrator in the configuration u have mentioned. I think so. It's been so long I studied this Ele. Ckt. subjects. Anyway.

2nd Ckt. is also Schmitt Trigger with +ve Vi offset
