Hello,
I made a 4 RC filter stages to convert pulse waves to sine waves.
pulse source: 0V ~ 1.8V, f= 2.45GHz, duty cycle= 50%
r= 600ohm, c= 100fF, load= port(resistance= 1M ohm)
to get -Vout ~ +Vout, I add AC coupling capacitor(C17) between 4th capacitor and load.
However, the voltage at both ends of C17 shows the same result...
I think it's because the output voltage is like a rectified voltage.
How can I get a sine wave with the DC offset removed?
