Hi,
A simple track and hold circuit could be found in the attachment.
This Track and Hold circuit is used for the front end of high speed flash ADC, say 5Ghz.
By using 5GHZ as sampling frequecy, when the input frequency is 2.5GHz, the simulation shows that the output signal is distorted very seriously.
I want to improve the bandwidth.what can I do? Can someone give some suggestion and direction?
To increase the input bandwidth, which parameter can I change?
or can I add some circuit? Is there some good reference available?
Do anyone have a detailed parameter for this circuit?
I want to get some inputs for how to solve these problems.
Thanks in advance
