Nettet5. okt. 2014 · The gain of a non-inverting single Op-Amp circuit is given by: H ( s) = 1 + Z 2 Z 1, where Z 2 is the feedback impedance (in our case, the capacitor), and Z 1 the equivalent paralell combination of R 3 and R 4, which we will call R p. H ( s) = 1 + Z 2 Z 1 = 1 + 1 R p C s = R p C s + 1 R p C s. The gain at DC (zero frequency), according to the ... Nettet10. jun. 2011 · This circuit is used to bring the level of swing of V0 to a positive direction. When V in ranges from 0 to positive voltage, D2 is reverse biased and thus V0 = -V sat. When V in ranges from 0 to negative voltage, D2 is forward biased and D1 goes into avalanche condition. Thus V0 = V Z + V D2. Op-amp-comparator-circuit.
