Yes. i checked with it. whenever i give higher voltage to the (+) circuit works properly.
but the problem is i cant change the value of resistors, i have another unit with the same circuit and it works properly .
@Dominik Przyborowski There is no difference between inputs.. both the inputs are Zero!!!

@LvW There is no feed back to the input. its just output of another opamp to the D15 cathode. D15 blocks the voltage . It is a Single supply voltage.
I have problem in a circuit , where I have OPAMP with inputs low . But at output I'm getting 20volts ... I have attached the circuit image below. OPAMP has biasing voltage of 20 volts
the problem is solved.
Thank you all ..
i changed the transistor and checked the circuit , now its working :) ..
might be the diode within the transistor was weak , so it was not switching.
now i am getting 5v @collector
Hi,
i was working on a circuit in which i got BC177 PNP transistor. getting 3.8 voltage @base of transistor , but still its not switching. Transistor is in working condition.
how much voltage exactly required by the transistor to switch ?
the transistor circuit is followed by the voltage...
Actually i am checking the voltage vs time transient analysis. but i want delay vs time for comparison of two schematic .
how we can compare two schematic waveform in one chart?
Hi i am doing project on tanner eda v13.0. while doing layout, for connecting metal 1 and resistor which contact i have to use? and also i wanted to know that how to check the resistor value in layout design ?
thankyou.
