SELF_BUFFERED_SERIES_CLIPPER

Provides negative clipping of sine.wave input, using 2620 opamps with diodes as linear OR gate. When input voltage is greater than reference voltage, A1-D1 turns on and input voltage appears at output. When Ein falls below Vref, A2-D2 provide Vref as output signal. With 2620, circuit gives good performance to above 10 kHz. For positive clipping, reverse diode connections and return R1 to +15 V. Circuit provides low output impedance.-W.
