Circuits designed by Dave Johnson, P.E. :
  • 200MHz400MHz VOLTAGE controlled OSCILLATOR
    If you need a clean emitter coupled logic (ECL) type signal between 200MHz and 400MHz this circuit works fine. It uses four voltage-controlled capacitors to change the frequency.
  • AUDIO FREQUENCY DIGITAL NOISE GENERATOR
    When you need to test an audio circuit with broadband noise, this circuit works great. It uses just three inexpensive C-MOS ICs that generate a series of output pulses whose widths vary randomly. I included a level control pot.
  • 12V TOUCH SWITCH EXCITER CIRCUIT
    This circuit is designed to generate a 20KHz pseudo sine wave signal that can power about 50 remote touch activated switch circuits.  It can support a cable length of about 2500 feet.  A typical remote switch circuit is also shown as well as a receiver circuit for those switches.
  • 40KHZ LED TEST SIGNAL GENERATOR
    This 40KHz crystal controlled oscillator circuit drives an infrared LED with powerful 40ma pulses.  The circuit can be used to test optical communications circuits, designed to receive 40KHz modulated light signals.
  • CMOS INVERTER 125KHz LC OSCILLATOR
    This circuit uses a single CMOS inverter to form a series resonant LD oscillator.   The values shown set the oscillation at about 125KHz but other frequencies are possible by changing the main LC values.
