Hello,

i am using shown integrator in a circuit which has two phase.  after 1st phase of the circuit is over, the integrator has some output (say 0.3 mV) .in the beginning of second phase , i need to provide the negative of output voltage (say -0.3 mV) to the input of integrator. how can i provide the -ive output voltage to input? is it possible to use a switch and by flipping the capacitor C1 and C2 position or just by changing their polarity using switch?

wat is this

no ..it's proper polarity
