Circuits Designed by Dave Johnson, P.E. :
  • N-CH AND P-CH TRANSISTORS FORM PUSH-PULL DRIVER
    This circuit can produce high speed output signals with fast rise and full times. The unique change pump action allows the voltage of the upper P-ch device to range from millivolts to hundreds of volts. The output current is only limited by the rating of the transistors. I have used this circuit beyond 2MHz.
