50－MHz_TRIGGER

Published:2009/7/8 4:20:00 Author:May | From:SeekIC

This has a stable trigger 100 mV sensitivity at 50 MHz. The FETs comprise a simple high-speed buffer and the LT1016 compares the buffer's out-put to the potential at the trigger level potentiometer, which can be of either polarity. The 10-KΩ resistor provides hysteresis, eliminating chattering caused by noisy input signals. To calibrate this circuit, ground the input and adjust the input zero control for 0 V at Q2's drain terminal.
