Please change the value of RB1 to 330k ohm (value in the figure is 270 ohm) and also change the value of R2 to 0.5k ohm (value in the figure is 1k ohm).
first put the frequency=1k Hz then gradually increase the frequency to see which frequency is the best to operate (because I myself have forgotten the best value of frequency for this circuit )
Hi dear isurunalaka*
what's your BW ?
what voltage you will to give ?
my friend there are many way for this , but at first you must say your details that you want .
Best wishes
