hi,
What limits the bandwidth of an active high pass filter? What is the bandwidth for high pass filter. thanks.

I am unable to answer your question...what is ur need.../
anyway positon of zero will determine bandwidth as per control systems engg.
and also ' lower' cutoff frequency(parameter normally used for mentioning high pass filter as a cutooff frequency present in high frequency) is determined by circuit element in other words by means of circuit time constant(inv.proportional to freq) whereas there will rolloff for practical high pass filter when frequency is increased this due presnce of parallel capacitance inherently within filter especially the junction capacitance of transistor..this will form higher cutoff frequency... but no rolloff for ideal high pass filter that cannot be realizied....for ideal high pass filter bandwidth will be from lower cutoff frequency to infinite frequency something starnge to share.....
still to be expolred

huji,
The primary limiter is the gain-bandwidth product of the OP Amp.
