b.  1st Simulation breadboard prototype.

4-d. We now see that at higher supply voltage ratings, OPAMPS will not work.  We will keep the first opamp since it is a buffer to protect our input source. Thus, we are looking at other approaches to compensate for our present voltage gain stage (stage 1).  

1.  We are trying Emitter follower topologies to up our voltages.

2.  We are going to order some MOSFET’s once we have decent results from BJT’s.  From Dr. Winton’s Electronic Circuit’s 2 course, the only difference in the two is the phase shifting.  

3.  Once we get our voltage up to standards, we will then up stage 2 to standards depending on how higher voltages and current effects stage 2.  We do predict many changes needed, since the components that we have are not expensive.  Using better and more expensive brands will be needed do to heat from power efficiency.     

4.  For our voltage and current source, we will use a rectifier, which will draw voltage and current from a wall socket.  Then it will convert it to DC source power.  We are not
