A half wave precision rectifier is implemented using an op amp, and includes the diode in the feedback loop. The output of precision rectifier is applied to another terminal of summing amplifier. There are ways of safely using an operational amplifier as a comparator – if the output stage is designed to be used that way - as in a voltage limiting operational amplifier – or if clamping is added externally that prevents the output from saturating. In this active version, the problem is solved by connecting the diode in the negative feedback loop. PSPICE results for the circuits are presented. FIGURE 11: Half-Wave Rectifier with RL =1kΩ.
