hi to all,
how to find a peak to peak value of any arbitary wave form (say square wave) , in which we have to read positive peak and negative peak. Here i am attaching bundle, can any sugest how to use it,
thanks

The peak detector is based on a S/H module, in turn, being an analog solution, uses
charge on a capacitor as its memory. PSOC 3 datasheet for S/H does not specify the droop
rate, which is leakage caused. Q = C x V, I = C dV/dT. So if you have a leakage of 1 uA, working
with 5 pF, you can compute how much it will droop in your timeframe of concern. The way around this
is a servo loop with a DAC, or easier, A/D the peak and hold that in memory that does not forget.
