hello, everyone
I have following questions about track and hold circuit.
(1)What's the difference between track and hold(T/H) and sample and hold
(2)how to T/H improve ADC input bandwidth?
by holding the input to a DC level while ADC is converting?
(3)how to improve the speed of T/H, in other words, what's the difference between
1GS/s and 3GS/s T/H?
(4)in some papers, sampling rate of ADC is 2GS/s, but why 2GHz input bandwidth is required?
(5)in some papers, for example, why the input bandwidth is 0.8GHz-1.5GHz, not 0-1.5GHz?
thanks for your reply.
