You might be able to find unsuitable resistor values that eliminate bistable behaviour.

Click to expand... k so how to overcome that ? i mean how can i choose values ? what should i connect there ?

The resistors in this simulation are high enough so that current draw is always under 1 mA (with a 6V supply). It should work with hardware.

Click to expand... oh i see lots of theories are there for me still have to apply in practice well sir i saw mostly designs with green baground & green grey circuit diagrams & waveform , which soft you are using ? I too want to design such things for analysis
