Document Summary
Page 1 of 5 - nov 9, 2 0 1 0. N on-inverting ampli er ( gure 14 . 11) Notes: we want to check if there is negative feedback, the input does not need to be applied to the inverting input to achieve negative feedback. V1 can be found from voltage divider: ( or use kvl) Page 2 of 5 - nov 9, 2 0 1 0. Output impedance: v0 is independent of the load we attached to it, thus the output impedance is zero. Page 3 of 5 - nov 9, 2 0 1 0. Can use the switch to send this to zero. Applications of op-amps: treat the integrator circuit, the gain circuit, and summer circuit like an operational block. Page 4 of 5 - nov 9, 2 0 1 0. Solving differential equations with circuits: trying to nd x(t) given u(t) (forcing function)
