High voltage limiter
Hi,
I need to design a high gain receiver that must be able to withstand (block) high voltage (350 V) pulses (the receiver must amplify the very small signals that follow this pulse).
Any idea on how to block the high voltage pulses in order to protect the receiver? Originaly I used a resistor and a pair of diodes, but the resistor generates too much thermal noise that gets amplified in the receiver.
Thanks,
