Hi, i have a circuit diagram and i would like to simulate the circuit in order to obtain a graph of Gain(dB) vs Frequency. but i don't know how to do it ... can anyone tell me how i can simulate it using orcad pspice ...i added the vpulse as i don't know whatelse to put there. thanks



regards,

put an ac source at the input with a magnitude of 1 and then measure the output using the db(v(out)) command -- assuming your output node is called "out". For the ac analysis you need to specify the beginning frequency, end frequency and the no of points per decade. Look into the simulation setting for ac analsysis

Best regards,
