Hi,
I'm trying to understand the circuit below. I know the comparator voltage reference is 13/2 = 6.5V and is set at the inverting input of the comparator. However, my confusion is about the input voltage in the non-inverting pin. Is it affected by capacitor C1? When the FET is turned on, R1 and R2 form a resistor divider, but how is it affected by C1?
NOTE: FET M1 is not actually a FET. It's an inverter like this one.
