For a full wave rectifier, it is given by the expression, r = 1⁄4√3. For a half wave rectifier the ripple factor is also expressed as a function of capacitance and load resistance, r = 1⁄2√3. Introduction. The proposed circuit performs positive half-wave, negative half-wave, positive full-wave, and negative full-wave rectification into a single circuit. I choose to use two stages: a single wave precision rectifier (i.e. Djukic 266 diodes D4 and D2 conducting. /Differences [107 /k 118 /v] The precision rectifier or super diode is an arrangement achieved with one or more op-amps (operational amplifiers) in order to have a circuit perform like a rectifier and an ideal diode.
