suggest an amplifier/comparator

[kumaran1988]

Please suggest a mos circuit to amplify 5mV peak spike like input to square pulses(full swing). The width of a spike is around 1nsec.
A sample input is shown in the file attached.[/img]

Wow,
GHz bandwidth,
<5mV input offset and noise...

is it possible? i don't know...

 

[kumaran1988]

Must be possible.. All it requires is a high speed comparator or amplifier.
Any idea.?

looks like you want to amplify some kind of radiation detector pulses. if it is correct then please use a Charge Sensitive Amplifier.


also keep in mind the thermal noise issues, cool the circuit.

@hock

Did you notice the pink area at the top of the plot? It's not any radiation sensor output. The signal is from a combinational circuit.

is is important power dissipation or not?

Since the signal looks synchronous, maybe you can use a clocked comparator? 1ns might be enough time for a fast comparator to do it's thang...
