Hi there.
Im developing a PMOS ring oscillator. On the end of this oscillator i've set up an amplifier to convert the oscillating signal to a square wave. This circuit has been simulated in LTspice, as follows:
Now in Spice, the square wave switches between 0 and 0.6 volts. Although as you can see below, when i mimic this circuit on a breadboard, i get a square wave which switches between 0 and 4.1 Volts (which is better for my application ofcourse).
Can anyone explain why the difference between the voltages in simulation and in practice is so big?
Thanks in advance!
