I've been trying to get a multiple feedback lowpass filter to work. With this schematic.
The filter works in the simulation but when i try to build it, it gives no output.
The op amp used to build it is a MCP6002 dual op amp with a rail to rail supply. I'm using 5v and 0v to power the op amps and im supplying a 1v sine wave.
I've read online that i might have to use a vref bias voltage to get it to work but i can't find too much about this and i'm unsure as to why it's not working.
Any help would be appreciated.
