Simulating the MOSFET rectifier
Before firing up the MOSFET rectifier circuit from yesterday on a breadboard I thought I'd try simulating it with LTspice, here is the schematic: MOSFET rectifier entered into LTspice I'm still taking baby steps on LTspice - for some reason I thought it would be time to update to the latest version. This really didn't make any difference. I also had trouble with the simulation and I thought it might be due to the way I was applying the AC to the rectifier. So a transformer was added using L1 and L2. I kept the ratio at 1:1 and just fed L1 with 1.414 x 6 V to get the peak input voltage of 8.5 volts. And I didn't see the TL084 opamp as an option so I selected what appears to be the Linear Technology equivalent (DIP, quad, JFET inputs) LT1058. At first the circuit did seem to simulate full wave rectification but when I tried adding a capacitor on the output the voltage didn't come up to near the peak as it should with only a string of high value resistors as a...
